Subject: [PATCH AUTOSEL 4.9 2/4] sfc: Don't use netif_info before net_device setup

From: Erik Ekman <erik@...o.se>

[ Upstream commit bf6abf345dfa77786aca554bc58c64bd428ecb1d ]

Use pci_info instead to avoid unnamed/uninitialized noise:

[197088.688729] sfc 0000:01:00.0: Solarflare NIC detected
[197088.690333] sfc 0000:01:00.0: Part Number : SFN5122F
[197088.729061] sfc 0000:01:00.0 (unnamed net_device) (uninitialized): no SR-IOV VFs probed
[197088.729071] sfc 0000:01:00.0 (unnamed net_device) (uninitialized): no PTP support

Inspired by fa44821a4ddd ("sfc: don't use netif_info et al before
net_device is registered") from Heiner Kallweit.
