fea681da | 50 | .B sk98lin |
c13182ef MK |
51 | is the Gigabit Ethernet driver for |
52 | Marvell and SysKonnect network adapter cards. | |
53 | It supports SysKonnect SK-98xx/SK-95xx | |
54 | compliant Gigabit Ethernet Adapter and | |
35478399 | 55 | any Yukon compliant chipset. |
5b539973 | 56 | .PP |
c13182ef MK |
57 | When loading the driver using insmod, |
58 | parameters for the network adapter cards | |
59 | might be stated as a sequence of comma separated commands. | |
60 | If for instance two network adapters are installed and AutoNegotiation on | |
61 | Port A of the first adapter should be ON, | |
35478399 | 62 | but on the Port A of the second adapter switched OFF, one must enter: |
5b539973 | 63 | .PP |
1ae6b2c7 AC |
64 | .in +4n |
65 | .EX | |
66 | insmod sk98lin.o AutoNeg_A=On,Off | |
67 | .EE | |
68 | .in | |
5b539973 | 69 | .PP |
62f38a5f MK |
70 | After |
71 | .B sk98lin | |
72 | is bound to one or more adapter cards and the | |
0daa9e92 | 73 | .I /proc |
9ee4a2b6 | 74 | filesystem is mounted on your system, a dedicated statistics file |
af02f8e6 | 75 | will be created in the folder |
0daa9e92 | 76 | .I /proc/net/sk98lin |
c13182ef | 77 | for all ports of the installed network adapter cards. |
35478399 | 78 | Those files are named |
951d2863 MK |
79 | .IR eth[x] , |
80 | where | |
0daa9e92 | 81 | .I x |
c13182ef | 82 | is the number of the interface that has been assigned to a |
35478399 | 83 | dedicated port by the system. |
5b539973 | 84 | .PP |
c13182ef | 85 | If loading is finished, any desired IP address can be |
35478399 | 86 | assigned to the respective |
0daa9e92 | 87 | .I eth[x] |
62f38a5f | 88 | interface using the |
fa72df69 | 89 | .BR ifconfig (8) |
c13182ef MK |
90 | command. |
91 | This causes the adapter to connect to the Ethernet and to display a status | |
92 | message on the console saying "ethx: network connection up using port y" | |
35478399 | 93 | followed by the configured or detected connection parameters. |
5b539973 | 94 | .PP |
62f38a5f MK |
95 | The |
96 | .B sk98lin | |
c13182ef MK |
97 | also supports large frames (also called jumbo frames). |
98 | Using jumbo frames can improve throughput tremendously when | |
99 | transferring large amounts of data. | |
100 | To enable large frames, the MTU (maximum transfer unit) size | |
101 | for an interface is to be set to a high value. | |
102 | The default MTU size is 1500 and can be changed up to 9000 (bytes). | |
103 | Setting the MTU size can be done when assigning the IP address | |
35478399 | 104 | to the interface or later by using the |
fea681da | 105 | .BR ifconfig (8) |
c13182ef MK |
106 | command with the mtu parameter. |
107 | If for instance eth0 needs an IP | |
108 | address and a large frame MTU size, | |
35478399 | 109 | the following two commands might be used: |
5b539973 | 110 | .PP |
1ae6b2c7 AC |
111 | .in +4n |
112 | .EX | |
113 | ifconfig eth0 10.1.1.1 | |
114 | ifconfig eth0 mtu 9000 | |
115 | .EE | |
116 | .in | |
5b539973 | 117 | .PP |
fea681da | 118 | Those two commands might even be combined into one: |
5b539973 | 119 | .PP |
1ae6b2c7 AC |
120 | .in +4n |
121 | .EX | |
122 | ifconfig eth0 10.1.1.1 mtu 9000 | |
123 | .EE | |
124 | .in | |
5b539973 | 125 | .PP |
33a0ccb2 | 126 | Note that large frames can be used only if permitted by |
2694f8dd | 127 | your network infrastructure. |
c13182ef MK |
128 | This means, that any switch being used in your Ethernet must |
129 | also support large frames. | |
130 | Quite some switches support large frames, | |
35478399 | 131 | but need to be configured to do so. |
c13182ef MK |
132 | Most of the times, their default setting is to support only |
133 | standard frames with an MTU size of 1500 (bytes). | |
134 | In addition to the switches inside the network, | |
135 | all network adapters that are to be used must also be | |
136 | enabled regarding jumbo frames. | |
14268ff3 | 137 | If an adapter is not set to receive large frames, it will simply drop them. |
5b539973 | 138 | .PP |
fea681da MK |
139 | Switching back to the standard Ethernet frame size can be done by using the |
140 | .BR ifconfig (8) | |
141 | command again: | |
5b539973 | 142 | .PP |
1ae6b2c7 AC |
143 | .in +4n |
144 | .EX | |
145 | ifconfig eth0 mtu 1500 | |

149 | The Marvell/SysKonnect Gigabit Ethernet driver for Linux is able to |
150 | support VLAN and Link Aggregation according to | |
151 | IEEE standards 802.1, 802.1q, and 802.3ad. | |
33a0ccb2 | 152 | Those features are available only after installation of open source modules |
35478399 | 153 | which can be found on the Internet: |

c13182ef | 407 | parameter will result in a merged configuration of those settings. |
35478399 | 408 | This is due to |
15079abb | 409 | the fact, that the per-port parameters (e.g., |

c13182ef MK |
415 | Interrupt moderation is employed to limit the maximum number of interrupts |
416 | the driver has to serve. | |
417 | That is, one or more interrupts (which indicate any transmit or | |
418 | receive packet to be processed) are queued until the driver processes them. | |
35478399 | 419 | When queued interrupts are to be served, is determined by the |
0daa9e92 | 420 | .I IntsPerSec |
c13182ef MK |
421 | parameter, which is explained later below. |
422 | Possible moderation modes are: | |
e4bd7c17 | 423 | .IR None , |
951d2863 | 424 | .IR Static , |
fea681da | 425 | or |
951d2863 | 426 | .IR Dynamic ; |
0daa9e92 | 427 | .I None |
c13182ef MK |
428 | is the default. |
429 | The different modes have the following meaning: | |

0daa9e92 | 431 | .I None |
c13182ef MK |
432 | No interrupt moderation is applied on the adapter card. |
433 | Therefore, each transmit or receive interrupt is served immediately | |
35478399 | 434 | as soon as it appears on the interrupt line of the adapter card. |
5b539973 | 435 | .IP |
0daa9e92 | 436 | .I Static |
c13182ef MK |
437 | Interrupt moderation is applied on the adapter card. |
438 | All transmit and receive interrupts are queued until | |
439 | a complete moderation interval ends. | |
440 | If such a moderation interval ends, all queued interrupts | |
441 | are processed in one big bunch without any delay. | |
35478399 | 442 | The term |
0daa9e92 | 443 | .I Static |
c13182ef MK |
444 | reflects the fact, that interrupt moderation is always enabled, |
445 | regardless how much network load is currently passing via a | |
446 | particular interface. | |
447 | In addition, the duration of the moderation interval has a fixed | |
35478399 | 448 | length that never changes while the driver is operational. |
5b539973 | 449 | .IP |
0daa9e92 | 450 | .I Dynamic |
c13182ef MK |
451 | Interrupt moderation might be applied on the adapter card, |
452 | depending on the load of the system. | |
453 | If the driver detects that the system load is too high, | |
454 | the driver tries to shield the system against too much network | |
455 | load by enabling interrupt moderation. | |
36546c38 | 456 | If\[em]at a later time\[em]the CPU utilization decreases |
14268ff3 | 457 | again (or if the network load is negligible), the interrupt |
35478399 | 458 | moderation will automatically be disabled. |
5b539973 | 459 | .IP |
c13182ef MK |
460 | Interrupt moderation should be used when the driver has to |
461 | handle one or more interfaces with a high network load, | |
36546c38 | 462 | which\[em]as a consequence\[em]leads also to a high CPU utilization. |
c13182ef | 463 | When moderation is applied in such high network load situations, |
523869f6 | 464 | CPU load might be reduced by 20\[en]30% on slow computers. |
5b539973 | 465 | .IP |
c13182ef MK |
466 | Note that the drawback of using interrupt moderation is an increase of |
467 | the round-trip-time (RTT), due to the queuing and serving of | |
35478399 | 468 | interrupts at dedicated moderation times. |
fea681da MK |
469 | .TP |
470 | .BI IntsPerSec= i,j,... | |
471 | This parameter determines the length of any interrupt moderation interval. | |
62f38a5f | 472 | Assuming that static interrupt moderation is to be used, an |
0daa9e92 | 473 | .I IntsPerSec |
fea681da | 474 | parameter value of 2000 will lead to an interrupt moderation interval of |
c13182ef MK |
475 | 500 microseconds. |
476 | Possible values for this parameter are in the range of | |
477 | 30...40000 (interrupts per second). | |
35478399 | 478 | The default value is 2000. |
5b539973 | 479 | .IP |
33a0ccb2 | 480 | This parameter is used only if either static or dynamic interrupt moderation |
c13182ef | 481 | is enabled on a network adapter card. |
35478399 | 482 | This parameter is ignored if no moderation is applied. |
5b539973 | 483 | .IP |
fea681da | 484 | Note that the duration of the moderation interval is to be chosen with care. |
75b94dc3 | 485 | At first glance, selecting a very long duration (e.g., only 100 interrupts per |
fea681da | 486 | second) seems to be meaningful, but the increase of packet-processing delay |
c13182ef MK |
487 | is tremendous. |
488 | On the other hand, selecting a very short moderation time might | |
fea681da MK |
489 | compensate the use of any moderation being applied. |

527 | This mode requires a network configuration in which the | |
75b94dc3 | 528 | two ports are able to "see" each other (i.e., there |
