From 6e5650896fe47398e49e3d81af60cc60dbb09e6e Mon Sep 17 00:00:00 2001 From: Brian Poole Date: Fri, 11 Oct 2024 15:57:52 -0400 Subject: [PATCH] ice(4): properly use kernel option RSS Header ice_rss.h uses the kernel RSS interface if option RSS is defined. However when ice_rss.h is included by ice_lib.h there is no prior inclusion of ice_opts.h to set RSS causing ifdef RSS to always fail. Add ice_opts.h to the top of ice_lib.h (like ice_iflib.h) so RSS can be defined when ice_rss.h is parsed. With that in place, compilation fails due to a missing defintion of ICE_DEFAULT_RSS_HASH_CONFIG. It is defined in ice_rss.h only when RSS is not defined. Since this define is not part of the kernel RSS interface but ice-specific, it should always be defined. Move its definition outside of ifdef RSS.
