Subject: i40e: Enable Geneve offload for FW API ver > 1.4 for XL710/X710 devices
X-Git-Tag: v4.1.12-92~189^2~116
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=cb0a97be8098d8e37ad1a608f9db2c880d815f50;p=users%2Fjedix%2Flinux-maple.git

i40e: Enable Geneve offload for FW API ver > 1.4 for XL710/X710 devices

Orabug: 22342532

This patch makes sure we check the GENEVE offload capable flag before
we attempt offload.
It also enables the Capability for XL710/X710 devices with FW API
version higher than 1.4
