From ebe5e3c64241bbdc256e9828392fa452bc2bfd7e Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 26 Mar 2014 21:18:39 -0700 Subject: [PATCH] net: bcmgenet: set RBUF_SKIP_FCS based on UniMAC CRC forwarding When the UniMAC block is configured to forward the CRC as part of the Ethernet frame (priv->crc_fwd_en, set by default), enabling the hardware RX checksum block unveiled that the dma_rxchk_bit was never set in the per-packet status bits (dma_flag in bcmgenet_desc_rx). This would make the chksum_ok variable to be never set to 1, and the networking stack would have to compute the packet checksums, which takes a substantial amount of time. In order for the RXCHK block to properly compute the packet checksum in hardware, we also need to set the RBUF_SKIP_FCS bit accordingly. Signed-off-by: Florian Fainelli Signed-off-by: David S.
