SVN rev 214219 on 2010-10-22 19:30:56Z by yongari
Add workaround for BCM5906 A1 controller silicon bug. When
auto-negotiation results in half-duplex operation, excess collision
on the ethernet link may cause internal chip delays that may result
in subsequent valid frames being dropped due to insufficient
receive buffer resources. The workaround is to choose de-pipeline
method as a flow control decision for SDI. De-pipeline method
allows only 1 data in TxMbuf at a time such that a request to RDMA
from SDI is made only when TxMbuf is empty. Thanks for david for
providing detailed errata information.
