Yes, but I think this has nothing to do with the subject. I think MCP controllers have a silicon bug that does not generate TX completion interrupts under certain conditions/controller models. The PR indicates what was really happened which also indicates possible silicon bug. nve(4) also seems to have some workaround for that but I wanted to verify it since we don't know what binary blob did during controller initialization. The message just shows informational message and does not reset controller so I think that edge case is already handled by nfe(4). _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
