net/udp: correct linger timeout
...
UDP linger timeout will be wrongly converted to UINT_MAX by _SO_TIMEOUT() when it is set to 0,
net/socket/socket.h:
|
| # define _SO_TIMEOUT(t) ((t) ? (t) * MSEC_PER_DSEC : UINT_MAX)
net/udp/udp_close.c:
|
| if (_SO_GETOPT(conn->sconn.s_options, SO_LINGER))
| {
| timeout = _SO_TIMEOUT(conn->sconn.s_linger);
| }
this change will correct this behavior, if the linger is set to 0, the timeout value should be 0

net/devif_poll: optimize device buffer alloc in txpoll
...
Allocate the device buffer only if the protocol really need to send data.
not all protocols require the driver to prepare additional iob before
sending, especially UDP, each iob reserves l2/l3 header in advance
after prepare write buffer, net device could reuse this entry to send directly

net_local: fix error when work with epoll
...
epoll_wait collects revent by checking fds->revent,
but local_socket will copy fds to the other two private pollfd shandow struct,
then the pipe_poll will not be able to update fds->revent directly,
so need local_socket save fds and implement a private poll_notify function
to passing revent to original fds->revent.

net/devif: fix devif_poll loop logic
...
Previously, the devif_poll works in this flow:
devif_poll_xx -> bstop = callback -> continue if !bstop -> poll another
Now we split the polling and callback, so it should work like:
devif_poll_connections -> return true if callback need to be called
-> bstop = callback -> loop if !bstop -> poll again
Conditions:
poll_connections == 0, d_len == 0, break, return 0
poll_connections == 1, d_len == 0, break, return 1 (other stop case,
don't callback)
poll_connections == 1, d_len > 0, callback == 1, break, return 1
poll_connections == 1, d_len > 0, callback == 0, loop
