 Hi Team,
 
 Thanks for your patience and assistance on this case.
 We've not removed "wm_pkt_stats" and "wm_print_stats" in NetBSD 7.1 and we
 use WM_T_I354 chip type.
 I've attached the output you've requested. I've taken the kernel live core
 last time when we faced this issue and the WM PHY was active.
 wm_reset doesn't help in to recover the issue state and device timeout log
 keeps on piling after wm_reset.
 Please let me know if any further details is needed.
 
 Regards,
 Aravind M.
