Bug Description

VNF vEPG 2.1/1.10
vRouter 3.2.8:
Set of features:
0100010001000010 1 000000000000011
Connectivity
working
vRouter 4.1.1:
Set of features:
0100010001000010 1 001100110000011
Connectivity
Not working
7 VIRTIO_NET_F_GUEST_TSO4 (7)
8 VIRTIO_NET_F_GUEST_TSO6 (8)
11 VIRTIO_NET_F_HOST_TSO4 (11)
12 VIRTIO_NET_F_HOST_TSO6 (12)

The test include:
- configuration on vrouter side with mrgbuf off and GSO/GRO on
409f19a7 ==> 0100 0000 1001 1111 0001 1001 1010 0111 -- > connectivite OK

- configuration on vrouter side with mrgbuf on and GSO/GRO off
409f8027 ==> 0100 0000 1001 1111 1000 0000 0010 0111 -- > connectivite NOK

In all the cases, the VNF send the following bits :
430020 => 0000 0000 0100 0011 0000 0000 0010 0000 (mrgbuff, TSO)

and in all cases, the negotiated feature bit is :
30020 => 0000 0000 0000 0011 0000 0000 0010 0000

The question is why if the result is the same, in one side when the mrgbuf off and GSO/GRO on the connectivity is Ok and when mrgbuf on and GSO/GRO off the connectivity is NOK ?

Mergeable buffer issue with Ericsson vEPG

Closes-bug: #1806441
Issue with the workaround done for the qemu
bug. Workaround to use the previous negotiated
feature list to be used only after a vrouter
restart.
