2012-04-16pcnet: Properly handle TX requests during Link FailJan Kiszka
As long as we have no link and we aren't in internal loopback mode, no packet must be sent. Instead, LCAR needs to be set in any active TX descriptor and also CERR in CSR0. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2011-11-01pcnet: Add link state supportJan Kiszka

2011-11-01pcnet: Move BCR defines to headerJan Kiszka
This moves BCR defines to the common header and immediately makes use of them to add BCR_APROMWE, replacing the open-coded write check in pcnet_aprom_writeb. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
