During testing, I enabled the RSS kernel configuration option= so the driver would use the system-wide standard RSS key instead of the custom= ice key. I was surprised to see even after rebooting, the driver was still using the ice key. My debugging led me to ice_lib.h where ice_rss.h is included. However, I do= n't believe there is a prior include of ice_opts.h, so when ice_rss.h is parsed, RSS is not defined causing ice-specific definitions to be used. I added ice_opts.h to the include list above ice_rss.h and re-compiled. I hit a second problem within ice_rss.h where ICE_DEFAULT_RSS_HASH_CONFIG is only defined inside the !RSS block. I believe this is an oversight, probably hidden by the previous bug. That variable is used in ice_lib.c so it cannot depend on the state of the RSS option. Therefore, I moved the definition outside of the RSS/!RSS blocks. With these two changes, in the included patch file, I observed the ice driv= er using RSS settings from the kernel, not ice-specific values. Looking at the FreeBSD-13.0 and HEAD branches, it looks like the same problems are present. --=20 You are receiving this mail because: You are the assignee for the bug.=
