Cover letter [RFC/RFT PATCH 0/6] rtl8187: Reduce delays to reduce startup time
The current version of the rtl8187 driver contains a large number of msleep() commands that cause initialization to take a long time. 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.
