Subject: [dpdk-dev] tailroom in rte_mbuf
Date: Thu, 12 Jun 2014 11:03:13 +0530 [thread overview]
Message-ID: <CA+U1=Gtd5ex41JVF-25_1RYDUW4mphSMvGWwCW+Eq4vCWbHs0A@mail.gmail.com> (raw)
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
