Harald Welte 90ef31873c add module parameter "sleep_on_enobufs" to work around -ENOBUFS AF_PACKET sockets have these incredibly useful semantics in where for both non-blocking and blocking I/O, they will tell you the socket is rwite-able, but then still return -1 and sett errno=ENOBUFS if the current socket buffer / transmit queue is full. All we can do is usleep and retry. The new module parameter, if set to non-zero, determines the number of microseconds we shall sleep before any retry. If set to zero, the existing behavior is preserved: TTCN_error(). Related: SYS#5343 Change-Id: I1608403d94a10ae52c7e1de0f1b02687b048c01e	2021-01-29 20:30:55 +01:00

AF_PACKET sockets have these incredibly useful semantics in where
for both non-blocking and blocking I/O, they will tell you the
socket is rwite-able, but then still return -1 and sett errno=ENOBUFS
if the current socket buffer / transmit queue is full.

All we can do is usleep and retry.  The new module parameter, if set
to non-zero, determines the number of microseconds we shall sleep before
any retry.  If set to zero, the existing behavior is preserved:
TTCN_error().
