This avoids duplicating the same code into all drivers that need this information.

Also let's move the allocation out of the declaration block so it's easier to read. Fixes: 4a5eccaa9350 ("mac80211: Show pending txqlen in debugfs.")

This does not only simplify the code, it also allows the use of more efficient and more secure implementations, especially on platforms where SIMD ciphers have a considerable setup cost.

This makes the code more understandable, and allows platforms to implement cmac(aes) in a more secure (*) and efficient way than is typically possible when using the AES cipher directly. So replace the crypto_cipher by a crypto_shash, and update the aes_s2v() routine to call the shash interface directly. * In particular, the generic table based AES implementation is sensitive to known-plaintext timing attacks on the key, to which AES based MAC algorithms are especially vulnerable, given that their plaintext is not usually secret. Time invariant alternatives are available (e.g., based on SIMD algorithms), but may incur a setup cost that is prohibitive when operating on a single block at a time, which is why they don't usually expose the cipher API.
