[Intel-wired-lan] [PATCH net v2] igb: Fix XDP with PTP enabled

[Tyler S]

Thanks for this work; I was having trouble using XDP on my I354 NIC until this.

Hopefully I have not err'd backporting it to 5.10 -- but I'm seeing
jumbo frames dropped after applying this (though as previously
mentioned, non-skb/full driver XDP programs do now work).

Looking at the code, I'm not sure why that is.
