SRIO Functional Description

For multi-segment messages, if the transfer is unsuccessful after 256 times of credit request for the first
segment, the TXU moves to the next queue in the round-robin loop. The TXU tries to send the unsent
message again the next time around the loop. After the first segment is granted outbound credit and is
sent to the physical layer for transmission, all subsequent segments are given 64K attempts to gain
outbound credit. If the TXU is unsuccessful after the 64K attempts, a completion code of 111b is written to
the buffer descriptor, and the message is cancelled with no attempt to resend.

When the device is powered on, the SRIO peripheral is in a disabled state. Before any SRIO specific
initialization can take place, the peripheral needs to be enabled; otherwise, its registers cannot be written,
and the reads will all return a value of zero.
