Subject: net: mana: Add support for PF device 0x00C1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=53a65db20a4f3fe6c01b1f789f9eae6b1244910f;p=thirdparty%2Fkernel%2Flinux.git

net: mana: Add support for PF device 0x00C1

Update the device id table to include the new device id 0x00C1.
This device's BAR layout is similar to VF's, update the function,
mana_gd_init_registers(), accordingly.
