6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vlad Dogaru <vdogaru@xxxxxxxxxx>
[ Upstream commit 521992337f67f71ce4436b98bc32563ddb1a5ce3 ]
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")
