Revert "net: macsec: preserve ingress frame ordering"
This reverts commit ab046a5d4be4c90a3952a0eae75617b49c0cb01b.
It was trying to work around an issue at the crypto layer by excluding
ASYNC implementations of gcm(aes), because a bug in the AESNI version
caused reordering when some requests bypassed the cryptd queue while
older requests were still pending on the queue.
This was fixed by commit 38b2f68b4264 ("crypto: aesni - Fix cryptd
reordering problem on gcm"), which pre-dates ab046a5d4be4.
Herbert Xu confirmed that all ASYNC implementations are expected to
maintain the ordering of completions wrt requests, so we can use them
in MACsec.
On my test machine, this restores the performance of a single netperf
instance, from 1.4Gbps to 4.4Gbps.
