Subject: bnxt_en: Return correct RSS indirection table entries to ethtool -x.
X-Git-Tag: v5.10.7~1943^2~301^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=adc38ac66745949ce12c1861c1a25f3ef93df1f8;p=platform%2Fkernel%2Flinux-rpi.git

bnxt_en: Return correct RSS indirection table entries to ethtool -x.

Now that we have the logical indirection table, we can return these
proper logical indices directly to ethtool -x instead of the physical
IDs.
