Subject: [Intel-wired-lan] [PATCH iwl-next v2 0/4] igb: Add support for AF_XDP zero-copy
Date: Tue, 11 Jul 2023 13:47:01 +0200 [thread overview]
Message-ID: <20230711114705.22428-1-sriram.yagnaraman@est.tech> (raw)
The first couple of patches adds helper funcctions to prepare for AF_XDP
zero-copy support which comes in the last couple of patches, one each
for Rx and TX paths.
I will attach performance numbers to this thread in a couple of days.
v1->v2:
- Use batch XSK APIs (Maciej Fijalkowski)
- Follow reverse xmas tree convention and remove the ternary operator
use (Simon Horman)
Sriram Yagnaraman (4):
igb: prepare for AF_XDP zero-copy support
igb: Introduce XSK data structures and helpers
igb: add AF_XDP zero-copy Rx support
igb: add AF_XDP zero-copy Tx support
