Summary
igc: set tx buffer type for SMD frames
Details

In the Linux kernel, the following vulnerability has been resolved:

igc: set tx buffer type for SMD frames

Sashiko pointed out that igcfpeinitsmdframe() initializes igctxbuffer fields for an SMD skb, but does not set the buffer type: https://sashiko.dev/#/patchset/20260415025226.114115-1-kohei%40enjuk.jp

Since igctxbuffer entries are reused, a stale XDP or XSK type can remain and make TX completion use the wrong cleanup path.

Set the buffer type to IGCTXBUFFERTYPESKB.
