[5/17] net: ipv4: Add scaffolding to change completion function signature

Commit Message

Herbert Xu Feb. 6, 2023, 10:22 a.m. UTC

This patch adds temporary scaffolding so that the Crypto API
completion function can take a void * instead of crypto_async_request.
Once affected users have been converted this can be removed.
