Excuse me for the misunderstanding. Most probably this is not an issue in VPP.
In the mentioned 'previous version of vpp (git version 45207e0fb2) the
af_packet_create_v2 api was used, so the memory increase is expected.
So, the question had lapsed.

Subject: VNET Device Drivers; increased memory footprint for af_packet v3
Hello fellow VPP developers!
I experienced an increase in memory allocation related to af_packet v3.
VPP is built from source from git version: e416893a5. The AF_PACKET interface
is created by the go bin-api call AfPacketCreateV3 (invoking
af_packet_create_v3 api call in VPP).
The amount of memory assigned to an af_packet socket appears to be 135MB per
af_packet socket. In VPP based on git version 45207e0fb2 the memory assigned to
an af_packet socket was around 20MB.
Is this memory allocation increase intentional? If not is it a known issue? Any
workaround or patch exist (if it is a bug and it was fixed)?
Thanks in advance,
