Subject: [net-next V3 07/12] net/mlx5e: Move the TLS resync check out of the function
Date: Mon, 21 Sep 2020 19:46:59 -0700 [thread overview]
Message-ID: <20200922024704.544482-8-saeed@kernel.org> (raw)
In-Reply-To: <20200922024704.544482-1-saeed@kernel.org>
From: Maxim Mikityanskiy <maximmi@mellanox.com>
Before this patch, mlx5e_ktls_tx_handle_resync_dump_comp checked for
resync_dump_frag_page. It happened for all WQEs without an SKB,
including padding WQEs, and required a function call. Normally, padding
WQEs happen more often than TLS resyncs. Take this check out of the
function and put it to an inline function to save a call on all padding
WQEs.
