- First version of driver that enables interrupts · e12d04f0
  Wesley W. Terpstra authored 12 years ago
```
  * Had to re-order initialization; pci_device_enable must precede pci_enable_msi
  * Must enable master mode on the device to receive MSIs and/or bus master
  * Report the address/data from the bridge

This never appeared until now because it only failed if two records appeared at once.

- pcie-wb: Two bugs: · f14c9e5c
  Wesley W. Terpstra authored 12 years ago and Alessandro Rubini committed 12 years ago
```
  Don't overflow the buffer! Compare the index for overflow not the position.
  Read/write of 0 returns 0 even when non-blocking.

- pcie-wb: PCI express allows posted operations to cut-in-line versus non-posted operations. · 7fa187f0
  Wesley W. Terpstra authored 12 years ago and Alessandro Rubini committed 12 years ago

This would break the read (non-posted) and write (posted) ordering that Wishbone depends on.

Fixed bugs in kernel etherbone:
  record_len was shadowed by redeclation
  wrote maximum of possible bytes instead of minimum
  added non-blocking IO support
