| |
2.6.32-stable review patch. If anyone has any objections, please let us know.
------------------ From: Wey-Yi Guy <wey-yi.w.guy@intel.com>
commit 4d80d7210bb5a36a18978d1305b44375ecb857d9 upstream.
Multiple MPDUs can be aggregated, transmitted, and finally acknowledged together using a single BA frame. Block ACK (BA) contains bitmap size of 64*16 bits so the maximum frame count is 64. The default value of aggregation frame count suggested by uCode is 31 to achieve best performance.
