[lwip-devel] [patch #8882] Vector improvements

[Simon Goldschmidt]

Update of patch #8882 (project lwip):

         Planned Release:                    None => 2.0.0 Beta2

Follow-up Comment #13:

Sorry for taking so long again.

Could we combine the TCP path of lwip_sendmsg() with the UDP path (allocate a
netbuf + PBUF_REF for each iovec)? Then we would have to change
lwip_netconn_do_send() to handle the netbuf for TCP.

(Although lwip_netconn_do_send() doesn't return the number of written bytes,
but I'm not sure what would be correct here: retry or return less than
requested).

Either way, since sendmsg() is new to 2.0.0, let's sort this out before the
release.
