If -ignore_readdir_race is present, [ENOENT] errors caused by deleting a
file after find has read its name from a directory are ignored.
Formerly, -ignore_readdir_race did nothing.

the code masks ki_stat with SZOMB to compare with SZOMB, but ki_stat
is not a mask.

is not correct. The code works by accident because gzFile is
currently defined as void *, and internally it would be casted from
or to its real type.
A newer version of zlib will instead define it as a pointer to a
specific type pointer (namely, struct gzFile_s *). This therefore
would cause stricter checks and compiler would catch this type
mismatch.
This change does not cause any changes to the resulting binary,
as validated with md5(1).

- Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs.
These are available as t3_tom and t4_tom modules that augment cxgb(4)
and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as
usual with or without these extra features.
- iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the
works and will follow soon.
Build-tested with make universe.
30s overview
============
What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the
capabilities of an interface:
# ifconfig -m | grep TOE
Enable/disable TCP offload on an interface (just like any other ifnet
capability):
# ifconfig cxgbe0 toe
# ifconfig cxgbe0 -toe
Which connections are offloaded? Look for toe4 and/or toe6 in the
output of netstat and sockstat:
# netstat -np tcp | grep toe
# sockstat -46c | grep toe
