Subject: ice(4): add SIOCGIFRXR support
To: tech@openbsd.org
Date: Tue, 7 Oct 2025 13:58:45 +0200

While trying to figure out why ice(4) fails to receive any packets on
sparc64 I stumbled over the fact that ice(4) is missing SIOCGIFRXR
support and so systat mbuf does not show the queues.

This implements this by mostly stealing the code from ixl(4).
