[lwip-devel] [bug #23240] recv_udp increases counters for available receives before netbuf is actually posted

[Simon Goldschmidt]

Follow-up Comment #14, bug #23240 (project lwip):

I guess the patch looks quite good except for the usage of conn->recv_avail
in lwip_ioctl() case FIONREAD: it is casted to u16_t, which should be
converted to s16_t, too.

Except for that, I guess it's OK as a fix, but I'm not in a position to
actually test it.
