  MFC r204155,204219:
  r204155:
    Increase PCIe maximuim read request size to 2048. Because re(4) uses
    Tx DMA burst size 2048, I beleive PCIe maximum read request size
    also should match to the value of Tx DMA burst size. With this
    change I can get more than 800Mbps for TCP bulk transfers.
    Previously I was not able to get more than 700Mbps. If I enable TSO
    it now shows 927Mbps.
  
  r204219:
    Add TSO on VLANs. Because re(4) has a TSO limitation for jumbo
    frame, make sure to update VLAN capabilities whenever jumbo frame
    is configured.
    While I'm here rearrange interface capabilities configuration. The
    controller requires VLAN hardware tagging to make TSO work on VLANs
    so explicitly check this requirement.
