Since the cleanup task gve_tx_cleanup_tq already runs off of interrupts, I am thinking of fixing t= his by having gve_xmit_br marking itself as stopped when it sees ENOBUFS and the cleanup thread wake it up when room is made. --=20 You are receiving this mail because: You are the assignee for the bug.=
