Re: [PATCH v3 3/4] crypto/net/ipv6: sr: Switch to using crypto_pool

The conversion to use crypto_pool has the following upsides:
- now SR uses asynchronous API which may potentially free CPU cycles and
  improve performance for of CPU crypto algorithm providers;
- hash descriptors now don't have to be allocated on boot, but only at
  the moment SR starts using HMAC and until the last HMAC secret is
  deleted;
- potentially reuse ahash_request(s) for different users
- allocate only one per-CPU scratch buffer rather than a new one for
  each user
- have a common API for net/ users that need ahash on RX/TX fast path
