This series of patches include revisions that were found by looking at the latest version of the vendor's driver (rtl8187B_linux_26.1036.0708.2008), and others that were found to be OK with testing. To keep each of the patches relatively small, these changes are split into 6 parts. The changes in them are as follows: 1. Remove all delays of greater than 1 sec. 2. Remove the msleep(1) that immediately follow calls to rtl8225_write_phy_ofdm(). 3. Remove the msleep(1) that immediately follow calls to rtl8225_write_phy_cck(). 4. Remove the msleep(1) that immediately follow calls to rtl8225_write(). 5. Remove the nsleep() calls from rtl8187_write_phy(), rtl8225_write_bitbang(), and rtl8225_write_8051(). 6. Remove the msleep(10) that preceeds a channel change. Before these changes, routine rtl8187b_init_hw() took 15.82 sec to execute. It now takes 3.76 sec. Signed-off-by: Larry Finger ---
