This series introduces iov_tail to convey frame information
between functions.
This is only an API change, for the moment the memory pool
is only able to store contiguous buffer, so, except for
vhost-user in a special case, we only play with iovec array
with only one entry.
v5:
- store in the pool iovec array with several entries
v4:
Prepare to introduce iovec array in the pool:
- passe iov_tail rather than pool to ndp,icmp, dhcp, dhcpv6 and arp
- remove unused pool macros
- add memory regions in the pool structure, this will allow us to use
the buf pointer to store the iovec array for vhost-user
v3:
Address comments from David
Laurent Vivier (29):
arp: Don't mix incoming and outgoing buffers
iov: Introduce iov_slice(), iov_tail_slice() and iov_tail_drop().
iov: Update IOV_REMOVE_HEADER() and IOV_PEEK_HEADER()
tap: Use iov_tail with tap_add_packet()
packet: Use iov_tail with packet_add()
packet: Add packet_data()
arp: Convert to iov_tail
ndp: Convert to iov_tail
icmp: Convert to iov_tail
udp: Convert to iov_tail
tcp: Convert tcp_tap_handler() to use iov_tail
tcp: Convert tcp_data_from_tap() to use iov_tail
dhcpv6: move offset initialization out of dhcpv6_opt()
dhcpv6: Extract sending of NotOnLink status
dhcpv6: Convert to iov_tail
dhcpv6: Use iov_tail in dhcpv6_opt()
dhcp: Convert to iov_tail
ip: Use iov_tail in ipv6_l4hdr()
tap: Convert tap4_handler() to iov_tail

ndp: use iov_tail rather than pool
packet: remove PACKET_POOL() and PACKET_POOL_P()
packet: remove unused parameter from PACKET_POOL_DECL()
packet: add memory regions information into pool
packet: use buf to store iovec array
