Many chips are not able to deal with non-consecutive rx antenna selections
and respond with calibration errors, reset errors, etc.
When an antenna is selected as a tx antenna, also flag it for rx to avoid
chip issues.

This patch configures data rates to firmware using bitrate mask

Earlier we used to only update band information in this handler
which will be used later for ibss network. Due to recent
modifications in ibss join code we don't need to do that.

In mwifiex_set_rf_channel() ibss specific flags were unnecessarily
getting modified for infra and AP mode. This patch removes
mwifiex_set_rf_channel() function and adds equivalant code in infra,
ibss and AP path.
For ibss, now we are chosing band based on channel type and basic
rates provided in ibss join request. We can start ibss network in
A only, B only, G only, BG, BGN, AN mode.

2) Currently we don't have command to set Tx data rate, so
mwifiex_rate_ioctl_set_rate_value() function and related code
can be removed.
3) "ds_rate" filled by mwifiex_ret_tx_rate_cfg() is never used.

1) Recently we removed set_channel cfg80211 handler. Also, cfg80211
blocks ibss connection requests if ibss network is already started
/joined. Hence the code to restart ibss network in new channel
(mwifiex_drv_change_adhoc_chan() function) becomes redundant.
2) mwifiex_bss_set_channel() function is redundant. It does some
error checking and calculate adhoc start band and adhoc channel.
Cfg80211 already takes care of error checking and provides correct
channel information to the driver. Adhoc start band is already
calculated in mwifiex_set_rf_channel() function.
Other associated code is also removed in this patch.

Commit d83579e2a50ac68389e6b4c58b845c702cf37516 incorporated some
changes from the vendor driver that made it newly important that the
calculated hardware version correctly include the CHIP_92D bit, as all
of the IS_92D_* macros were changed to depend on it. However, this bit
was being unset for dual-mac, dual-phy devices. The vendor driver
behavior was modified to not do this, but unfortunately this change was
not picked up along with the others. This caused scanning in the 2.4GHz
band to be broken, and possibly other bugs as well.
This patch brings the version calculation logic in parity with the
vendor driver in this regard, and in doing so fixes the regression.
However, the version calculation code in general continues to be largely
incoherent and messy, and needs to be cleaned up.

Currently VF queues and drivers may remain active during this test.
This could cause memory corruption or spurious test failures.
Therefore we reset the port/function before running these tests on
Siena.
On Falcon this doesn't work: we have to do some additional
initialisation before some blocks will work again. So refactor the
reset/register-test sequence into an efx_nic_type method so
efx_selftest() doesn't have to consider such quirks.
In the process, fix another minor bug: Siena does not have an
'invisible' reset and the self-test currently fails to push the PHY
configuration after resetting. Passing RESET_TYPE_ALL to
efx_reset_{down,up}() fixes this.

efx_end_loopback() iterates over an array of skb pointers of which
some may be null (if efx_begin_loopback() failed). It should not use
dev_kfree_skb_irq(), which requires non-null pointers. In practice
this is safe because it does not run in interrupt context and
therefore always ends up calling dev_kfree_skb(), which does allow
null pointers. But we should make that explicit.

Currently the VF driver is processing all of the transmits in interrupt
context. This can be messy since the Rx is all handled in NAPI and this

polling routines into just a pair of functions.

For most cases the ixgbevf driver will only ever contain a single Tx and
single Rx queue. In order to track that it makes more sense to use a
pointer instead of using a bitmap which must be search in order to locate

pointers and an iterator to access all rings on a given q_vector.

Typically, the return value desired for the failure of a function with an
integer return value is a negative integer. In these cases, the return
value is sometimes a negative integer and sometimes 0, due to a subsequent
initialization of the return variable within the loop.
