This change moves the lock so that it protects a call to __skb_dequeue().

Signed-off-by: Larry Finger <[email protected]>

The incorrect placement of a lock meant that the TX ring queue was not
protected. On one system, this led to freezes when running rtl8192ee.
When checking the other drivers to see which ones are affected, it was
discovered that several of them used identical code. Accordingly, this
routine was moved into core.c where all the drivers could share a single
copy.

In a number of places, kmalloc or valloc were used to acquire memory.
To ensure that these locations are correctly initialized, the calls were
changed to kzalloc and vzalloc. The change seems to have cleared a problem
that was causing HT operations to be cancelled.

In kernel 3.13.0-XX where XX is >= 32, Ubuntu has implemented the API
change that was introduced in mainline V3.15 by commit d8ca16db6bb2 ("mac80211:
add length check in ieee80211_is_robust_mgmt_frame()"). The result is that the
code in this repo gets it wrong for Ubuntu kernels. The result is
a kernel that crashes when using the corresponging driver. Thanks to user
"lenonk" at GitHub, there is a fix. I have not tested it as I do not use one
of the affected kernels; however, it looks correct.

In 3.18, the kernel contains options to compress the modules. When this

This callback routine pointer was added to driver rtl8192ee to help
fix the stability of the connection. One problem with that fix is that
this pointer is undefined for the rest of the drivers. To prevent
crashes, we need to test for a non-NULL pointer before we call the
routine.

When a beacon is transmitted, the "own" bit is not cleared. As a result, most
of the implementations of is_tx_desc_closed() will return false. This causes
the TX interrupt service routine to quit early and leak an IOMMU mapping.
By testing for a beacon before calling the above routine, this leakage is
prevented.

Signed-off-by: Larry Finger <[email protected]>

Transmission of a beacon while in AP mode does not generate an interrupt, thus
the TX interrupt service routine is not called, and the cleanup is handled in
a tasklet completion routine. Unfortunately, this routine does not release the
DMA mapping before it frees the skb.
