Subject: [dpdk-dev] [PATCH] net/mlx5: fix bit field compiling error
Date: Tue, 27 Oct 2020 01:24:45 +0800
Message-ID: <1603733085-271968-1-git-send-email-bingz@nvidia.com> (raw)

Some old compilers and old specification will not support bit field
with other types except integer or unsigned integer.
Since the next and previous items are 64b and/or 32b aligned, bit
field with "unsigned char" type will not save any space and the
compiler will complain.
Changing it to "unsigned int" type bit field will solve the issue.

Fixes: f711b60d400b ("net/mlx5: modify hash Rx queue objects")
