Subject: [Intel-wired-lan] [PATCH iwl-next v7 05/14] libie: add
bookkeeping support for control queue messages

From: Phani R Burra <redacted>

All send control queue messages are allocated/freed in libie itself
and tracked with the unique transaction (Xn) ids until they receive
response or time out. Responses can be received out of order,
therefore transactions are stored in an array and tracked though a
bitmap.

Pre-allocated DMA memory is used where possible. It reduces the driver
overhead in handling memory allocation/free and message timeouts.
