Subject: bnxt_en: Define the supported chip numbers.
X-Git-Tag: v4.1.12-92~126^2~8
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=019f0e920880465d6fbf8010860819df56cc6126;p=users%2Fjedix%2Flinux-maple.git

bnxt_en: Define the supported chip numbers.

Orabug: 23221795

Define all the supported chip numbers and chip categories.  Store the
chip_num returned by firmware.  If the call to get the version and chip
number fails, we should abort.
