https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D248652 --- Comment #28 from Vincenzo Maffione <vmaffione@FreeBSD.org> --- (In reply to Sylvain Galliano from comment #26) Thanks. I just figured out that there may be a major flaw introduced by the porting= of ixl to iflib. This flaw should couse too many writebacks from the NIC to re= port completed transmissions, even if iflib asks for a writeback once in a while. Can you please run again your tests on ixl with the latest patch? --=20 You are receiving this mail because: You are on the CC list for the bug.=
