Hello,
My application requires to reserve some tailroom in the packet mbuf after
the packet payload. I see that in the default configuration the packet mbuf
reserves only the headroom. When I send larger packets, the payload is
copied until the last byte of the packet mbuf before going to next mbuf.
I know I can do it by modifying the rte_pktmbuf_init and keep some tailroom
for myself.
But is there a parameter already available in DPDK which allows me to do
this. Do we need a patch for this ?
Regards,
Vivek Soni
