| |
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 1152dcc28c66a74b5b3f1a3ede0aa6729bfd48e4 upstream
Similar to 6000 and 1000 series, RTS/CTS is the recommended protection mechanism for 5000 series in HT mode based on the HW design.
Using RTS/CTS will better protect the inner exchange from interference, especially in highly-congested environment, it also prevent uCode encounter TX FIFO underrun and other HT mode related performance issues.
