In the commit title, it is better to describe a functional impact
rather than repeat the implementation of a fix.

This makes it easier for people looking for a fix for their specific
issue they are investigating.
And, on the contrary, it also makes it easier when looking for a
regression on a specific feature.

Here, "fix variable type" gives no clue that it is linked to packet
length or the protocol agnostic/raw pattern offloading feature.

So, I don't understand this part of the code, but I think a better
title would be:
net/ice: fix protocol agnostic offloading with big packets

Does it sound ok to you?
