3:0 Max XOFF Renewal 0x0
NC-SI Flow Control MAX XOFF Renewal (# of XOFF renewals
allowed).
0x0 = Disabled. Unlimited number of XOFF frames can be sent.
0x1 = Up to 2 consecutive XOFFs frames can be sent by the I210.
0x2 = Up to 3 consecutive XOFFs frames can be sent by the I210.
…

15:0 Token Timeout 0XFFFF
NC-SI HW-Arbitration TOKEN Timeout (in 16 ns cycles). In order to
get the value in NC-SI REF_CLK cycles, this field should be
multiplied by 4/5.
Notes:
1. Setting value to 0x0 disables the timeout mechanism.
2. The timeout must be no fewer than 32,000 REF_CLK cycles
(for example, the value of the field should be greater or equal
to 0x9C40).
