IPv4/IPv6 checksum offloading and VLAN tag insertion/stripping.
Since uether doesn't provide a way to announce driver specific offload
capabilities to upper stack, checksum offloading support needs more work
and will be done in the future.
Special thanks to Hayes Wang from RealTek who gave input.
- Add error handling for urtwn_(r88e_)read_rom() and
urtwn_efuse_*() functions.
- Remove code duplication between urtwn_efuse_read() and
urtwn_r88e_read_rom().
- Merge r88e_rom and (r92c_)rom structures
(only one of them can be used at the same time).
- Other minor fixes / improvements.
Tested with RTL8188EU, STA mode
(URTWN_DEBUG + USB_DEBUG, hw.usb.urtwn.debug=3, no visual differences).

- Split urtwn_tx_start() into urtwn_tx_data() and urtwn_tx_start()
(the last will be used for beacon updates / raw xmit path).
- Remove unneeded code from _urtwn_getbuf().
- Use CCK11 for data frames in 11b mode.
- Send EAPOL frames at 1 Mbps.
- Reduce code duplication in urtwn_tx_data().
- Fix sequence numbering.
- Add IEEE80211_RADIOTAP_F_WEP flag for encrypted frames.
- Check URTWN_RUNNING flag under lock.

32-bits aligned. Merge the two bounce buffers into a single one. Some
rough tests showed that the DWC OTG throughput on RPI2 increased by
10% after this patch.

The mbuf length fields must be set before m_adj() is called else
m_adj() will not always adjust the mbuf and an unaligned read
exception can trigger inside the network stack. This can happen on
platforms where unaligned reads are not supported. Adjust a length
check to include the 2-byte ethernet alignment while at it.

- Drop TSF initialization; device can discover it without our help.
- Do not touch R92C_BCN_CTRL_EN_BCN bit in STA mode.
- Add 'static' keyword for function definition.

Since r288350, ic_wme_task() is called via ieee80211_runtask(),
so, any additional deferring from the driver side is not needed.

- Move all files related to the LinuxKPI into sys/compat/linuxkpi and
its subfolders.
- Update sys/conf/files and some Makefiles to use new file locations.
- Added description of COMPAT_LINUXKPI to sys/conf/NOTES which in turn
adds the LinuxKPI to all LINT builds.
- The LinuxKPI can be added to the kernel by setting the
COMPAT_LINUXKPI option. The OFED kernel option no longer builds the
LinuxKPI into the kernel. This was done to keep the build rules for
the LinuxKPI in sys/conf/files simple.
- Extend the LinuxKPI module to include support for USB by moving the
Linux USB compat from usb.ko to linuxkpi.ko.
- Bump the FreeBSD_version.
- A universe kernel build has been done.

This doesn't free the mbuf upon error; the driver ic_raw_xmit method is still
doing that.

* Create ieee80211_free_mbuf() which frees a list of mbufs.
* Use it in the fragment transmit path and ath / uath transmit paths.
* Call it in xmit_pkt() if the transmission fails; otherwise fragments
may be leaked.
This should be a big no-op.

Now run(4) fetches parameters from ic->ic_wme.wme_params array, which is never initialized
(and can be safely removed). This patch replaces &ic->ic_wme.wme_params with
&ic->ic_wme.wme_chanParams.cap_wmeParams (contains parameters for local station;
used by other drivers with WME support).
