both values are valid "non-characters" [2] and must be mapped through
UTFs.

MFC the mpr(4) driver for LSI's 12Gb SAS cards.

This includes r265236, r265237, r265241 and r265261:

  Bring in the mpr(4) driver for LSI's MPT3 12Gb SAS controllers.

  This is derived from the mps(4) driver, but it supports only the 12Gb
  IT and IR hardware including the SAS 3004, SAS 3008 and SAS 3108.

  Some notes about this driver:
   o The 12Gb hardware can do "FastPath" I/O, and that capability is included in
     this driver.

   o WarpDrive functionality has been removed, since it isn't supported in
     the 12Gb driver interface.

   o The Scatter/Gather list handling code is significantly different between
     the 6Gb and 12Gb hardware.  The 12Gb boards support IEEE Scatter/Gather
     lists.

  Thanks to LSI for developing and testing this driver for FreeBSD.

Generate hardware notes for mpr(4) and bump copyright for 2014.
MFC r261533, r261536, r261537, and r263457.

r261533:
cxgbe(4): Use the port's tx channel to identify it to t4_clr_port_stats.

r261536:
cxgbe(4): The T5 allows for a different freelist starvation threshold
for queues with buffer packing.  Use the correct value to calculate a
freelist's low water mark.

r261537:
cxgbe(4): Use the rx channel map (instead of the tx channel map) as the
congestion channel map.

r263457:
cxgbe(4):  Recognize the "spider" configuration where a T5 card's 40G
QSFP port is presented as 4 distinct 10G SFP+ ports to the driver.

Lagg did not set the value of if_hw_tsomax, so when lagg
was stacked on top of network interfaces that set if_hw_tsomax,
tcp_output() would see the default value instead of the value
set by the network interface(s). This patch modifies lagg so that
it sets if_hw_tsomax to the minimum of the value(s) for the
underlying network interfaces.
MFC: r264517
Vlan did not set the value of if_hw_tsomax, so when vlan
was stacked on top of a network interface that set if_hw_tsomax,
tcp_output() would see the default value instead of the value
set by the network interface. This patch modifies vlan so that
it sets if_hw_tsomax to the value of the parent interface.
MFC: r264630
For NFS mounts using rsize,wsize=65536 over TSO enabled
network interfaces limited to 32 transmit segments, there
are two known issues.
The more serious one is that for an I/O of slightly less than 64K,
the net device driver prepends an ethernet header, resulting in a
TSO segment slightly larger than 64K. Since m_defrag() copies this
into 33 mbuf clusters, the transmit fails with EFBIG.
A tester indicated observing a similar failure using iSCSI.

The second less critical problem is that the network
device driver must copy the mbuf chain via m_defrag()
(m_collapse() is not sufficient), resulting in measurable overhead.

This patch reduces the default size of if_hw_tsomax
slightly, so that the first issue is avoided.
Fixing the second issue will require a way for the
network device driver to inform tcp_output() that it
is limited to 32 transmit segments.

MFC r260210 (by adrian@):
Add an option to enable or disable the small RX packet copying that

When doing RX packing, the RX copying isn't necessarily required.
MFC r263317, r263412, and r263451.

r263317:
cxgbe(4): significant rx rework.

- More flexible cluster size selection, including the ability to fall
  back to a safe cluster size (PAGE_SIZE from zone_jumbop by default) in
  case an allocation of a larger size fails.
- A single get_fl_payload() function that assembles the payload into an
  mbuf chain for any kind of freelist.  This replaces two variants: one
  for freelists with buffer packing enabled and another for those without.
- Buffer packing with any sized cluster.  It was limited to 4K clusters
  only before this change.
- Enable buffer packing for TOE rx queues as well.
- Statistics and tunables to go with all these changes.  The driver's
  man page will be updated separately.

r263412:
cxgbe(4): if_iqdrops statistic should include tunnel congestion drops.

r263451:
cxgbe(4): man page updates.
MFC r259382:

Read card capabilities after firmware initialization, instead of setting
them up as part of firmware initialization (which the driver gets to do
only if it's the master driver).

Read the range of tids available for the ETHOFLD functionality if it's
enabled.

New is_ftid() and is_etid() functions to test whether a tid falls within
the range of filter tids or ETHOFLD tids respectively.
