[-- Attachment #1 --] Sorry (again) for delaying weekly status report, here's status update from last week: * Submitted http://p4web.freebsd.org/@@194133?ac=10 Clear bit ioctls added (BIOCCRRXQMASK, BIOCCRTXQMASK, BIOCCROTHERQMASK) This enables to clear mask bit. http://p4web.freebsd.org/@@194138?ac=10 index size check on ioctl Just bug fix http://p4web.freebsd.org/@@194139?ac=10 implement queue affinity ioctl Now BIOCRXQAFFINITY/BIOCTXQAFFINITY are implemented. Also em(4) support added. http://p4web.freebsd.org/@@194258?ac=10 debug log in bpf_mtap caused panic, commented out Just bug fix http://p4web.freebsd.org/@@194262?ac=10 get queue affinity test code added. Simple test code for BIOCRXQLEN/BIOCTXQLEN/BIOCRXQAFFINITY/BIOCTXQAFFINITY. * Not submitted yet To reduce lock contention in bpf_*tap*, I'm trying to replace BPFIF_LOCK from mtx to rmlock. Right now it doesn't work and not yet to find out why. Diff attached this mail.
