Subject: [PATCH net 2/6] net/mlx5: HWS, Rightsize bwc matcher priority
Date: Tue, 11 Mar 2025 00:01:40 +0200	[thread overview]
Message-ID: <1741644104-97767-3-git-send-email-tariqt@nvidia.com> (raw)
In-Reply-To: <1741644104-97767-1-git-send-email-tariqt@nvidia.com>

From: Vlad Dogaru <vdogaru@nvidia.com>

The bwc layer was clamping the matcher priority from 32 bits to 16 bits.
This didn't show up until a matcher was resized, since the initial
native matcher was created using the correct 32 bit value.

The fix also reorders fields to avoid some padding.

Fixes: 2111bb970c78 ("net/mlx5: HWS, added backward-compatible API handling")
