Subject: [PATCH] [v4] PA Semi PWRficient Ethernet driver
Driver for the PA Semi PWRficient on-chip Ethernet (1/10G)
Basic enablement, will be complemented with performance enhancements
over time. PHY support will be added as well.
Signed-off-by: Olof Johansson <olof@...om.net>
---
v4 changes:
* Check for dma mapping error
* Sparse cleanups
* Moved some register offsets to enums
* Don't spin infinitely on interface shutdown
* Remove some more debug cruft
* Better ring wrapping
* More locking fixes
* Misc other cleanups
v3 changes:
* Added remove function
* Checking interrupt status in handler
* Misc cleanups w.r.t. ring handing (INFO/DESCR/BUFF are gone)
* Added locking of the rings
* Using PCI DMA for all buffers
* Setting the interrupt descriptor field to include interface number
* Added PCI vendor ID, it's been submitted to sf.net as well.
* Moved Kconfig entry to the 10GbE section
