Periodic NIC issues (?) with Protectli Vault, Intel i226-V

[meyergru]

I only assumed that the reset code was added later to Linux because it was missing in the FreeBSD driver, which otherwise looked like a port. I really did not do any software archeology. :-)

If that problem is handled in iflib in FreeBSD, it is not really needed in the hardware-specific driver.

If Intel knew that problem existed from the get-go, which would be implied if the hangup fix was there from the first commit, they should have better fixed it in hardware, though.

Unfortunately the -igc_aspm kernel didn't resolve my issue. It happened again this morning, and as usual bouncing the LAN interface with ifconfig down/up resolved it. There's nothing interesting in dmesg and the only recent entries in the syslog relate to a DHCP renewal for the WAN interface (which is not something I've seen in other instances).

I grabbed sysctl output again for the LAN interface before bouncing it in case it helps.
