SVN rev 216026 on 2010-11-29 01:34:43Z by yongari
MFC r215847:
Disable retrying RX descriptor loading. The counter is used to set
number of retry to be performed whenever controller found RX
descriptor was empty. RX empty interrupt is generated only when the
retry counter is over. Experimentation shows retrying RX descriptor
loading increased number of dropped frames under flow-control
enabled environments so disable it and have controller generate RX
empty interrupt as fast as it can.
While I'm here fix RXCSR_DESC_RT_CNT macro.
