--- Comment #13 from Mark Johnston <ma...@freebsd.org> --- (In reply to Andriy Gapon from comment #12) I don't quite understand the comment either, but it makes some sense to me that the sysctl hides the problem: the bug is that vmxnet3_isc_txd_credits_update() can be called multiple times in parallel, from an interrupt handler and from the transmit path. The latter happens when ifmp_ring_enqueue() drains the ring, and this is inhibited when abdicate == 0. But, I think concurrent calls to vmxnet3_isc_txd_credits_update() is still possible even with that setting, e.g., from _task_fn_tx(). -- You are receiving this mail because: You are the assignee for the bug.
