From: Martin Matuska <m...@freebsd.org> To: bug-follo...@freebsd.org, m...@freebsd.org Cc: Subject: Re: kern/155030: [igb] igb(4) DEVICE_POLLING does not work with carp(4) Date: Fri, 20 Apr 2012 09:18:50 +0200 The problem was actually in the configuration of the igb driver. Polling works only with hw.igb.num_queues=1 - and this is also described in code comments of if_igb.c: * Legacy polling routine : if using this code you MUST be sure that * multiqueue is not defined, ie, set igb_num_queues to 1. This should be: a) added to the manpage b) the driver should not attempt polling if hw.igb.num_queues > 1 -- Martin Matuska FreeBSD committer http://blog.vx.sk _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
