45c5d90b65 Evidently setup_rss needs to happen whenever bind_qsets is done. This fixes
a problem with jumbo frames when not using msi-x interrupts.

5c5df3da16 - fix qset to port binding as a proper fix for the problems encountered on the 4-port
- fix the use after free seen when sending packets small enough to fit as an immediate
   and bpf peers are present
 - update to firmware rev 4.7 along with various small vendor fixes

7ac2e6c362 Fixes for 4 port and small packet optimization
- remove cpl->iff panic - we can't know the port number from the rspq on the 4-port
- pick the ifnet based on the interface in the CPL header
- switch to using qset 0 for egress on the 4-port for now - may change
  when we start using RSS
- move ether_ifdetach to before the port lock gets deinitialized to avoid
  hang in the case where there are BPF peers (cxgb_ioctl is called indirectly
  when BPF peers are present)
- don't call t3_mac_reset if multiport is set, this was causing tx errors
  by misconfiguring the MAC on the 4-port
- change V_TXPKT_INTF to use txpkt_intf as the interfaces are not contiguous
- free the mbuf immediately in the case where the payload is small enough to be copied
  into the rspq
- only update the coalesce timer if for a queue if packets were taken off of it
- add in missed 20ms DELAY in initializaton vsc8211

- prompt MFC as this only applies to the 4-port which is currently completely
  broken - OK'd by kensmith

- reduce cpu usage by as much as 25% (40% -> 30) by doing txq reclaim more efficiently
   - use mtx_trylock when trying to grab the lock to avoid spinning during long encap loop
   - add per-txq reclaim task
   - if mbufs were successfully re-claimed try another pass
- track txq overruns with sysctl

bb38cd2fbc - switch adapter and port lock over to using sx so that resources
can be allocated atomically
- add debug macros for printing lock initialization / teardown
- add buffers to port_info and adapter to allow each lock to have a
  unique name
- destroy mutexes initialized by cxgb_offload_init
- remove recursive calls to ADAPTER_LOCK
- move callout_drain calls so that they don't occur with the lock held
- ensure that only as many qsets as are needed are initialized and
  destroyed

ef72318f0e - import new common code for the T304
- update to firmware version 4.1.0

- switch over to standard method for initializing cdevs (contributed by scottl@)
- break out timer_reclaim_task to be per-port
- move msix teardown into separate function
- fix bus_setup_intr for msi-x for the multi-port case so that msi-x resources
  are not corrupted on unload
- handle 10/100/1000 base-T media and auto negotiation
- bind qset to cpu even for singleq case
- white space cleanups
- remove recursive PORT_LOCK
- move mtu setting to separate function
- stop and re-init port when changing mtu
- replace all direct references to m_data with calls to mtod
- handle attach failure better by not trying to de-initialize
  taskqueues when they have not been allocated
- no longer default to jumbo frames

10faa56870 When building cxgb as a module make include paths relative to the driver's root.
This will make it possible to build the module out of tree against an older src tree.

- Quadruple the number of descriptors that can be reclaimed per pass
- only run reclaim twice per second
