Subject: [PATCH net-next 0/3] mlx4: better BIG-TCP support
Date: Tue, 6 Dec 2022 05:50:56 +0000 [thread overview]
Message-ID: <20221206055059.1877471-1-edumazet@google.com> (raw)
mlx4 uses a bounce buffer in TX whenever the tx descriptors
wrap around the right edge of the ring.
Size of this bounce buffer was hard coded and can be
increased if/when needed.
Eric Dumazet (3):
net/mlx4: rename two constants
net/mlx4: MLX4_TX_BOUNCE_BUFFER_SIZE depends on MAX_SKB_FRAGS
net/mlx4: small optimization in mlx4_en_xmit()
