Miscellaneous changes. Details below. Important changes flagged
with []. Using the driver with my Linksys WPC11 ver. 4, it seems to be receiving packets for a change. The WPC11 ver. 4 has a Maxim RF section. My no-name rtw with Philips RF section still does not receive any packets. Keep access-level (analog params > config[0123] registers > none) in sc_access. Add rtw_set_access for changing the access level. Make rtw_continuous_tx_enable and other subroutines use rtw_set_access instead of rtw_config0123_enable and rtw_anaparm_enable. Factor part of the chip-reset code into rtw_chip_reset1. Change the 'struct foo (*bar)[N]'-style arguments to 'struct foo *bar'-style arguments. Consolidate software/hardware Tx/Rx ring setup in rtw_hwring_setup, rtw_swring_setup. Add a new constant, SA2400_OPMODE_DEFAULTS, for the bits that we *always* set in the SA2400 OPMODE register. Factor some code out into rtw_sa2400_calibrate. (Inspired by the Linux driver.) [] When the receiver goes into underrun/overflow state, call a new subroutine, rtw_kick() that stops the Rx/Tx processes, resets the chip, reinitializes the Tx/Rx rings, and restarts Rx/Tx processes. (Inspired by the Linux driver.) [] In rtw_intr_rx, check for too-short packets before calling ieee80211_find_rxnode. I believe this will prevent a repeat of the MCHK exception I saw once on macppc. [] Use seconds-elapased as well as microseconds-elapsed to set the next "due date" for the timeout interrupt. This keeps the driver from programming the timeout to expire too early. [] In rtw_intr, read RTW_ISR at most 10 times, then get out. If the interface is not enabled (RTW_F_ENABLED), then get out. [] In rtw_stop, get out if the interface is not enabled (RTW_F_ENABLED). Block IPL_NET interrupts. Don't read/write any registers if the interface is invalid (RTW_F_INVALID). [] Call rtw_stop in rtw_detach.
