Hi all, Anybody got a chance to look into ?

BTW, am using below two patches for VF reset on DPDK 16.11

http://dpdk.org/ml/archives/dev/2016-June/040287.html  ::lib/librte_ether:
support device reset

<http://dpdk.org/ml/archives/dev/2016-June/040289.html>  ::ixgbe: implement
device reset on VF

Having few queries based above patches.

1) Are above patches are sufficient to reset VF ? Along with 2 patches, do
we need to have more fix ?

2) May know, Why above patches are not submitted, Were there any side
effect of both patches ?

3) Is the patch applicable to DPDK 2.1 also along with mailbox process
patch ?

4) Is there any plan to submit above fixes in latest dpdk code ?

Awaiting for the reply .. Thanks in advance.
