Make this manpage ready for hardware notes generation, add more Xrefs and perform
general cleanup.

In particular, don't claim rsu(4) devices can be configured with hostname(1)...

Add manpage for urtwnfw, the Realtek RTL8188CU/RTL8192CU firmware
module.  Also fix a few nits in urtwn.4.

Compared to the original revision, the list of supported chipsets was changed to
reflect those supported in this branch.

 fix mbuf leak if it does not fit in software queue

 264461:
 Commit various fixes for the SolarFlare drivers, in particular
 this set of patches fixes support for systems with > 32 cores.

 Details include

 sfxge: RXQ index (not label) comes from FW in flush done/failed events

 Change the second argument name of the efx_rxq_flush_done_ev_t and
 efx_rxq_flush_failed_ev_t prototypes to highlight that RXQ index (not label)
 comes from FW in flush done and failed events.

 sfxge: TXQ index (not label) comes from FW in flush done event

 Change the second argument name of the efx_txq_flush_done_ev_t prototype to
 highlight that TXQ index (not label) comes from FW in flush done event.

 sfxge: use TXQ type as label to support more than 32 TXQs

 There are 3 TXQs in event queue 0 and 1 TXQ (with TCP/UDP checksum offload)
 in all other event queues.

 264772:
 Check that port is started when MAC filter is set

 The MAC filter set may be called without softc_lock held in the case of
 SIOCADDMULTI and SIOCDELMULTI ioctls. The ioctl handler checks IFF_DRV_RUNNING
 flag which implies port started, but it is not guaranteed to remain.
 softc_lock shared lock can't be held in the case of these ioctls processing,
 since it results in failure where kernel complains that non-sleepable
 lock is held in sleeping thread.

 Both problems are repeatable on LAG with LACP proto bring up.

Avoid unsigned integer overflow which can cause
rman_reserve_resource_bound() to return incorrect results.

Continue the initial search until the first viable region is found.

Add a comment to explain the search termination test.

  Add an automatic resize support to the GEOM_PART class.

  When parent provider has been resized, the scheme specific G_PART_RESIZE

dd mrsas(4) driver from LSI official support of newer MegaRAID SAS
cards.  LSI has been maintaining this driver outside of the FreeBSD
tree.  It overlaps support of ThunderBolt and Invader cards that mfi(4)
supports.  By default mfi(4) will attach to cards.  If the tunable:
	hw.mfi.mrsas_enable=1
is set then mfi(4) will not probe and attach to these newer cards and
allow mrsas(4) to attach.  So by default this driver will not effect
a FreeBSD system unless mfi(4) is removed from the kernel or the
tunable is enabled.

mrsas(4) attaches disks to the CAM layer so it depends on CAM and devices
show up as /dev/daX.  mfiutil(8) does not work with mrsas.  The FreeBSD
version of MegaCli and StorCli from LSI do work with mrsas.  It appears
that StorCli only works with mrsas.  MegaCli appears to work with mfi(4)
and mrsas(4).

It would be good to add mfiutil(4) support to mrsas, emulations modes,
kernel logging, device aliases to ease the transition between mfi(4)
and mrsas(4).

Style issues should be resolved by LSI when they get committers approved.
The plan is get this driver in FreeBSD 9.3 to improve HW support.

Thanks to LSI for developing, testing and working with FreeBSD to
make this driver co-exist in FreeBSD.  This improves the overall
support of MegaRAID SAS.
