Stop reducing RA advertised ipv6 mtu by 16 - not needed.

This effectively reverts:

      Reduce advertised ipv6 mtu by 16 to fit ethernet header

      This is a temporary hack to workaround the inability of current
      kernel's ebpf bpf_skb_change_mode() function to prefix a 14-byte
      ethernet header on to a packet without going over the upstream
      (source, rawip) interface's mtu *before* we bpf_redirect() to
      the downstream (destination, ethernet) interface.

Test: flashed a flame with new kernel and it works at 1500 mtu
