+Subject: net: dp83822: disable false carrier interrupt
+
+From: Enguerrand de Ribaucourt <enguerrand.de-ribaucourt@savoirfairelinux.com>
+
+commit c96614eeab663646f57f67aa591e015abd8bd0ba upstream.
+
+When unplugging an Ethernet cable, false carrier events were produced by
+the PHY at a very high rate. Once the false carrier counter full, an
+interrupt was triggered every few clock cycles until the cable was
+replugged. This resulted in approximately 10k/s interrupts.
+
+Since the false carrier counter (FCSCR) is never used, we can safely
+disable this interrupt.
+
+In addition to improving performance, this also solved MDIO read
+timeouts I was randomly encountering with an i.MX8 fec MAC because of
+the interrupt flood. The interrupt count and MDIO timeout fix were
+tested on a v5.4.110 kernel.

+
+From: Enguerrand de Ribaucourt <enguerrand.de-ribaucourt@savoirfairelinux.com>
+
+commit 0e597e2affb90d6ea48df6890d882924acf71e19 upstream.
+
+Some RX errors, notably when disconnecting the cable, increase the RCSR
+register. Once half full (0x7fff), an interrupt flood is generated. I
+measured ~3k/s interrupts even after the RX errors transfer was
+stopped.
+
+Since we don't read and clear the RCSR register, we should disable this
+interrupt.

+The mentioned test-case still use an hard-coded-len sleep to

+
+On very slow VM and with debug build such timeout could be exceeded,

+Subject: selftests/net: pass ipv6_args to udpgso_bench's IPv6 TCP test
+
+From: Dimitris Michailidis <d.michailidis@fungible.com>
+
+commit b968080808f7f28b89aa495b7402ba48eb17ee93 upstream.
+
+udpgso_bench.sh has been running its IPv6 TCP test with IPv4 arguments
+since its initial conmit. Looks like a typo.

+Subject: usbnet: fix memory allocation in helpers
+
+From: Oliver Neukum <oneukum@suse.com>
+
+commit e65af5403e462ccd7dff6a045a886c64da598c2e upstream.
+
+usbnet provides some helper functions that are also used in
+the context of reset() operations. During a reset the other
+drivers on a device are unable to operate. As that can be block
+drivers, a driver for another interface cannot use paging
+in its memory allocations without risking a deadlock.
+Use GFP_NOIO in the helpers.
