[rt2x00-users] rt2800pci & hw crypto

Hi Ivo,

I saw you also merged a patch to enable hw crypto by default on rt2800pci.
The patch doesn't break anything but unfortunately it seems that hw crypto
doesn't work for received frames (only tried rt3052 SoC as usual) and
mac80211 decrypts them in sw.

So, I agree that we can simply turn hwcrypto on by default as it seems that
encrypting tx frames works just fine but we still have to investigate why
rx decryption fails.

Btw. I checked if rx decryption works by printing out RXD_W3_DECRYPTED for every
rx frame and it was never set :(
