7000 device series have a fix for this hardware feature. Stop disabling it, and get an improvement in Tx throughput. This feature allows the scheduler to fetch more frames on the fly while an A-MPDU is being built - which means that we can get larger A-MPDU. This, of course, give an improvement in the Tx throughput. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
