[PATCH 0/6] Allow more use of iovecs in pcap and tap interfaces

[David Gibson <david@gibson.dropbear.id.au>]

Laurent, sorry I didn't spot this earlier.

While working on other stuff I stumbled across these patches I wrote
quite a while back (part of a larger series on indefinite hiatus).
The first two patches have some overlap with the preliminary iovec
patches in the vhost-user series (and will certainly conflict).  I do
think the pcap interface here is slightly better than the one in the
vhost-user series, although I did ack that.

Stefano, if you've already applied / run tests for Laurent's series
then go ahead with it; I'll rework this on top of those.

David Gibson (6):
  util: Add helper to find offset into io vector
  pcap: Update pcap_frame() to take an iovec and offset
  util: Add write_remainder() helper
  pcap: Handle short writes in pcap_frame()
  pcap: Allow pcap_frame() and pcap_multiple() to take multi-buffer
    frames
  tap: Use write_remainder() in tap_send_frames_passt()
