The redesign of UDP flows required (or at least, suggested) a new
batch of prelininary changes that don't rely on the core of the flow
table rework.
David Gibson (11):
util: sock_l4() determine protocol from epoll type rather than the
reverse
flow: Add flow_sidx_valid() helper
udp: Pass full epoll reference through more of sock handler path
udp: Rename IOV and mmsghdr arrays
udp: Unify udp[46]_mh_splice
udp: Unify udp[46]_l2_iov
udp: Don't repeatedly initialise udp[46]_eth_hdr
udp: Move some more of sock_handler tasks into sub-functions
udp: Consolidate datagram batching
contrib: Add program to document and test assumptions about
SO_REUSEADDR
contrib: Test behaviour of zero length datagram recv()s
