From: Arnd Bergmann <arnd@xxxxxxxx> Atmel at76c502/at76c504/at76c506 is a PIO-only (PCMCIA, mini-PCI and Cardbus) 802.11b driver with incomplete CFG80211 support. Both PCMCIA and WEXT are deprecated, and there is little chance that anyone is still using this driver, so remove it. The related at76c50x USB driver uses MAC80211 and remains.
