If anyone has any objections, please let us know. ------------------ From: Wey-Yi Guy 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.
