      net: bcmgenet: set RBUF_SKIP_FCS based on UniMAC CRC forwarding · ebe5e3c6
      Florian Fainelli authored
      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.
