Thanks Damjan for the reply!
Following are my observations on Intel X710/XL710 pci-
1) I took latest code base from stable/vpp19.08 : Seeing error as "
*ethernet-input
l3 mac mismatch*"
* With Buffers 537600*

2) I have took latest code-base from stable/vpp2001 branch: Everything
looks fine with * Buffers 537600*
3) I took previous commit of "vlib: don't use vector for keeping buffer
indices in the pool " ie "df0191ead2cf39611714b6603cdc5bdddc445b57" :
Everything looks fine with *Buffers 537600.*
So this cleary shows the above commit will not fix our problem.
Thanks,
Chetan
