SVN rev 201839 on 2010-01-08 22:18:15Z by yongari
MFC r200526-200527,200529,200531-200533,200536
r200526:
Use PCIR_BAR instead of hard-coded value.
r200527:
Fix typo in register definition.
r200529:
Clear VGE_TXDESC_Q bit for transmitted frames. The VGE_TXDESC_Q bit
seems to work like a tag that indicates 'not list end' of queued
frames. Without having a VGE_TXDESC_Q bit indicates 'list end'. So
the last frame of multiple queued frames has no VGE_TXDESC_Q bit.
The hardware has peculiar behavior for VGE_TXDESC_Q bit handling.
If the VGE_TXDESC_Q bit of descriptor was set the controller would
fetch next descriptor. However if next descriptor's OWN bit was
cleared but VGE_TXDESC_Q was set, it could confuse controller.
Clearing VGE_TXDESC_Q bit for transmitted frames ensure correct
behavior.
r200531:
Use ANSI function definations.
r200532:
Remove unnecessary return statement.
r200533:
s/u_intXX_t/uintXX_t/g
r200536:
style(9).
