Thanks a lot guys for your support.
I have tried the patch by Yong Wang, stop and start functions are
working fine with out any crash.
I have noticed that tx/rx stats are being reset to 0. I am not sure if

ifconfig down and ifconfig up
Waterman/Navakanth, we've got some patches posted for the same by Yong Wang at
VMware. I haven't got the chance to look at it but if you can validate it, it'd
be great.
Thanks,

it out and it should work perfectly, you can give it a quick try.

I had tried with Stephen's patch but after stop is done and when we
call start it crashed at vmxnet3_dev_start()->
vmxnet3_dev_rxtx_init()->vmxnet3_post_rx_bufs() as buf_info is freed
and is not allocated again. buf_info is allocated in
vmxnet3_dev_rx_queue_setup() which would be called once at the
Yes I had a local copy working with couple of lines fix. But someone else, I
think Stephen added a fix patch for the same, and I assume if it's been merged,
should be working, so did not follow up later.
I don't have a VMware setup handy at moment but I think Waterman would have
more informati
