[dpdk-dev] [PATCH v2] net/virtio-user: fix implicit int to enum conversion

[Jianfeng Tan]

Implicit int to enum conversion is not allowed when icc is used as
the compiler. It raises the compiling error like,
    /.../dpdk/drivers/net/virtio/virtio_user/vhost_user.c(257):
        error #188: enumerated type mixed with another type
        msg.request = req;
                    ^
The fix is simple, change the type of parameter req to enum
vhost_user_request.

Fixes: 6a84c37e3975 ("net/virtio-user: add vhost-user adapter layer")
