[PATCH] backports: no longer support kernels < 3.10

[PATCH] backports: no longer support kernels < 3.10

[Johannes Berg]

From: Johannes Berg <johannes.berg@intel.com>

Since CRYPTO_CMAC was introduced in 3.10, and mac80211
depends on it, we basically get nothing out of it anyway.

I'm not removing the support code (yet) since it actually
compiles, and perhaps somebody has a need for (certain)
kernel versions lower than 3.10.

I guess this is not directly related to this change, right?

Oh, oops, yeah. I just thought I wanted to use the existing variable,
I'll split it out to another patch.
