9edef078cc cxgbetool(8): Add a subaction (tcbrss <n>) that can be used with "pass"
action to distribute traffic using the half of the VI's RSS indirection
table.

The value specified should either be the start of the VI's RSS slice
(available at dev.<ifname>.<inst>.rss_base since r339700) or the
midpoint (rss_base + rss_size/2).  The traffic that hits the filter will
use the first or second half of the indirection table respectively.
The indirection table can be populated in different ways to achieve
different kinds of traffic/load distributions.  For example, r339749
allows a netmap interface to have half the rx queues in the first half
of the table and the rest in the other.

ffcf81c99d cxgbetool(8): Require and validate only those inputs that are applicable
to the type of rate limiter being configured.  For example, the class
WRR scheduler doesn't need any kbps limits (it just needs the weights
for each class), the channel scheduler doesn't need anything except the
aggregate kbps to limit the channel to, and so on.

5fd1ea0810 Re-apply r190640.
- Restore local change to include <net/bpf.h> inside pcap.h.
This fixes ports build problems.
- Update local copy of dlt.h with new DLT types.
- Revert no longer needed <net/bpf.h> includes which were added
as part of r334277.

1131c927c4 cxgbe(4): Add support for Connection Offload Policy (aka COP).
COP allows fine-grained control on whether to offload a TCP connection
using t4_tom, and what settings to apply to a connection selected for
offload.  t4_tom must still be loaded and IFCAP_TOE must still be
enabled for full TCP offload to take place on an interface.  The
difference is that IFCAP_TOE used to be the only knob and would enable
TOE for all new connections on the inteface, but now the driver will
also consult the COP, if any, before offloading to the hardware TOE.

A policy is a plain text file with any number of rules, one per line.
Each rule has a "match" part consisting of a socket-type (L = listen,
A = active open, P = passive open, D = don't care) and a pcap-filter(7)
expression, and a "settings" part that specifies whether to offload the
connection or not and the parameters to use if so.  The general format
of a rule is: [socket-type] expr => settings

Example.  See cxgbetool(8) for more information.
[L] ip && port http => offload
[L] port 443 => !offload
[L] port ssh => offload
[P] src net 192.168/16 && dst port ssh => offload !nagle !timestamp cong newreno
[P] dst port ssh => offload !nagle ecn cong tahoe
[P] dst port http => offload
[A] dst port 443 => offload tls
[A] dst net 192.168/16 => offload !timestamp cong highspeed

The driver processes the rules for each new listen, active open, or
passive open and stops at the first match.  There is an implicit rule at
the end of every policy that prohibits offload when no rule in the
policy matches:
[D] all => !offload

This is a reworked and expanded version of a patch submitted by
Krishnamraju Eraparaju @ Chelsio.

component of cudbg.
