This series introduces iov_tail to convey frame information
between functions.
v10:
- rename iov_tail_drop() to iov_drop_header()
- rename pool_full() to pool_can_fit()
- replace NOLINTNEXTLINE(clang-analyzer-core.NonNullParamChecker)
by ASSERT(iov[i].iov_base);
- update iov_tail_clone() comment header
v9:
- address comments from David
v8:
- rebase
- rework the two last patches to store the iovec in the p->pkt array
v7:
- Add a patch to fix comment style of 'Return:'
- Fix ignore_arp()/accept_arp()
- Fix coverity error
- Fix several comments
v6:
- Replaced iov_slice() with the clearer iov_tail_clone()
for creating iovec subsets.
- Standardized local header variable names (to *_storage suffix).
- Renamed functions for better semantics (e.g., ignore_arp to
accept_arp, packet_data to packet_get).
- Corrected OPTLEN_MAX definition in TCP.
- Addressed minor logic issues (e.g., DHCPv6 FQDN flags, NDP null check).
- Updated ipv6_l4hdr() return type to boolean.
- Improved comments and documentation across several modules.
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
