https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200323 --- Comment #21 from Luiz Otavio O Souza,+55 (14) 99772-1255 <loos@FreeBSD.org> --- (In reply to Guy Helmer from comment #20) I studied this code (a lot) and found that some of sleeps are unnecessary. The cases we have to protect are: setting a new filter, setting a new interface and the flush/reset of buffers. The other cases can be dealt with some extra caution while handling the buffers (under the descriptor lock). This should cover your previous issues while still permit that we eliminate some of the sleeps. -- You are receiving this mail because: You are the assignee for the bug.
