SubjectRe: [PATCH] igc: updated TX timestamp support for non-MSI-X platforms

Hi James,

A couple of things that I should have pointed out earlier.

The subject line would be better if it was: "PATCH net" (to indicate
that the patch should be considered for the "net" tree, not "net-next").

Also, it could be made clearer that it's a fix, so the full subject line
could be like this:

"[PATCH net] igc: Fix TX timestamp support for non-MSI platforms"

Adding a "fixes" tag to the commit message would help, something like this:

Fixes: 2c344ae24501 ("igc: Add support for TX timestamping")
