[PATCH] vdpa/mlx5: Avoid warnings about shifts on 32-bit platforms
Clang warns several times when building for 32-bit ARM along the lines
of:
drivers/vdpa/mlx5/net/mlx5_vnet.c:1462:31: warning: shift count >= width
of type [-Wshift-count-overflow]
ndev->mvdev.mlx_features |= BIT(VIRTIO_F_VERSION_1);
^~~~~~~~~~~~~~~~~~~~~~~
This is related to the BIT macro, which uses an unsigned long literal,

[PATCH 2/5] get_driver_features from virito registers
This commit implements a new function ifcvf_get_driver_feature()
which read driver_features from virtio registers.
To be less ambiguous, ifcvf_set_features() is renamed to
ifcvf_set_driver_features(), and ifcvf_get_features()
is renamed to ifcvf_get_dev_features() which returns
the provisioned vDPA device features.

[PATCH v2 1/7] vdpa: fix improper error message when adding vdpa dev
In below example, before the fix, mtu attribute is supported
by the parent mgmtdev, but the error message showing "All
provided are not supported" is just misleading.
$ vdpa mgmtdev show
vdpasim_net:
supported_classes net
max_supported_vqs 3
dev_features MTU MAC CTRL_VQ CTRL_MAC_ADDR ANY_LAYOUT VERSION_1 ACCESS_PLATFORM
$ vdpa dev add mgmtdev vdpasim_net name vdpasim0 mtu 5000
