2afa1b3b64 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

8a63d29c6e 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

d87620abc9 net: downgrade iob priority of input/udp/icmp to avoid blocking devif 
When trying to use iperf2, we found it comsumes all the IOB when sending UDP packets, then devif_poll has no IOB to send the packet out, so speed drops to 0 and never recovers.

43cc4bd7bf 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.

34ade7a0b6 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

hashtable size=  2(1bit): -24% bandwidth @2k entries, -65% @10k entries
hashtable size=  4(2bits):-15% bandwidth @2k entries, -51% @10k entries
hashtable size= 32(5bits): -3% bandwidth @2k entries, -14% @10k entries
hashtable size=256(8bits): -1% bandwidth @2k entries,  -3% @10k entries

Note: Tested on worst performance, the earliest entry will be the worst.
