Subject: i40e: Cleanup the code with respect to restarting autoneg
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8eed76fa4885f1ed9f19f4d3a16dd24cebf09c19;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

i40e: Cleanup the code with respect to restarting autoneg

The restart-autoneg work around does not apply to X722.
Added a flag to set it only for the right MAC and right FW version
where the work around should be applied.
