2010-02-02be2net: use eq-id to calculate cev-isr reg offsetSathya Perla
cev-isr reg offset for each function is better calculated using (any) eq-id alloted to that function instead of using pci-func number(which does not work in some configurations...) Signed-off-by: Sathya Perla <sathyap@serverengines.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-01-21be2net: fix bug in rx page postingSathya Perla
Pages are posted to the rxq in such a way that more than one frag can share the page. The last frag that uses the page unmaps the page. In the case when a page is not fully used (due to lack of space in rxq) the last frag that uses the page is not being set as a "last_page_user"; instead, the next frag in the rxq is incorrectly being set. The fix has also been tested on ppc64 with 64k pages... Signed-off-by: Sathya Perla <sathyap@serverengines.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-11-06be2net: Bug fix to send config commands to hardware after netdev_registerAjit Khaparde
