2006-01-09[PATCH] ieee80211: enable hw wep where host has to build IVJohannes Berg
This patch fixes some of the ieee80211 crypto related code so that instead of having the host fully do crypto operations, the host_build_iv flag works properly (for WEP in this patch) which, if turned on, requires the hardware to do all crypto operations, but the ieee80211 layer builds the IV. The hardware also has to build the ICV. Previously, the host_build_iv flag couldn't be used at all for WEP, and not alone (with both host_decrypt and host_encrypt disabled) because the crypto algorithm wasn't assigned. This is also fixed. I have tested this patch both in host crypto mode and in hw crypto mode (with the Broadcom chipset).

Without this patch, if you try and use a key that has not been configured, for example: % iwconfig eth1 key deadbeef00 [2] without having configured key [1], then the active key will still be [1], but privacy will now be enabled.

Avoid repeated fragmentation when !host_encrypt. We only need do fragmentation when using host encryption. Otherwise we only need pass the whole packet to driver, letting driver do the fragmentation. 3. change the txb->payload_size to correct value FW will use this value to determine whether to do fragmentation. If we pass the wrong value, fw may cut on the wrong bound which will make decryption fail when we do host encryption.
