net: hns3: add support for dumping MAC umv counter in debugfs
This patch adds support of dumping MAC umv counter in debugfs, which will be helpful for debugging. The display style is below: $ cat umv_info num_alloc_vport : 2 max_umv_size : 256 wanted_umv_size : 256 priv_umv_size : 85 share_umv_size : 86 vport(0) used_umv_num : 1 vport(1) used_umv_num : 1 Signed-off-by: Jian Shen <shenjian15@huawei.com> Signed-off-by: Guangbin Huang <huangguangbin2@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
