From 9aac6c05a56289be7bb2ad4b6c34486dfa2d31eb Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Sat, 28 Oct 2023 21:58:39 -0700 Subject: [PATCH] RDMA/siw: Use crypto_shash_digest() in siw_qp_prepare_tx() Simplify siw_qp_prepare_tx() by using crypto_shash_digest() instead of an init+update+final sequence. This should also improve performance.
