[net-next,8/8] sfc: Separate netdev probe/remove from PCI probe/remove

Commit Message

Martin Habets June 20, 2022, 1:59 p.m. UTC

From: Jonathan Cooper <[e-mail]>

The netdev probe will be used when moving from the vDPA to EF100 BAR config.
The netdev remove will be used when moving from the EF100 to vDPA BAR config.

In the process, change several log messages to pci_ instead of netif_
to remove the "(unregistered net_device)" text.

The patches LGTM, but this one needs to get checkpatch'ed. 
Whitespace is off. Sorry for not catching this earlier.
Consider switching from the non-standard Co-authored-by 
to Co-developed-by for extra points.
