In code manipulating the TM State Low register of 802.11 cores, two different magic numbers are used to reference the 'G Mode Enable' bit. One of these, 0x20000000, is clear, but the other, (0x800 << 18), is not. This patch replaces both types with a defined constant. In addition, two bits in the TM State High registers are given definitions to help in following the code. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.
