mainline inclusion from mainline-v5.14-rc1 commit d59daf6a4ceedf342f349e94f1300e1598213252 category: feature bugzilla: NA CVE: NA DTS: DTS2021090315802
----------------------------
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
