[lwip-devel] [task #7421] Implement SO_RCVBUF

[Frédéric Bernon]

Update of task #7421 (project lwip):

        Percent Complete:                      0% => 10%

Follow-up Comment #2:

I attach a first patch (there is not the sockets.c/.h and opt.h part). It
just process UDP & RAW netconn (since TCP not need it).

It's mainly a new "netconn::recv_bufsize" field, initialized to 0xffffffff
(without any real limit), that can be set to a lower value to be able to limit
the number of bytes in the "netconn::recvmbox". It used the
"netconn::recv_avail" field (not very well protected for thread-safing).

Comments?
