drivers: net: add missing interrupt.h include

2017-07-18T18:13:41+00:00

these drivers use tasklets or irq apis, but don't include interrupt.h.
Once flow cache is removed the implicit interrupt.h inclusion goes away
which will break the build.

arcnet: add err_skb package for package status feedback

2017-06-29T19:26:13+00:00

We need to track the status of our queued packages. This way the driving
process knows if failed packages need to be retransmitted. For this
purpose we queue the transferred/failed packages back into the err_skb
message queue added with some status information.

arcnet: add netif_carrier_on/off for reconnect

2015-10-26T08:10:56+00:00

The arcnet device has no interrupt to detect if the link has changed
from disconnected to connected. This patch adds an timer to toggle the
link detection. The timer will get retriggered as long as the
reconnection interrupts accure. If the recon interrupts hold off
for >1s we define the connection stable again.

arcnet: com20020-pci: add led trigger support

2015-10-26T08:10:56+00:00

The EAE PLX-PCI card has special leds on the the main io pci resource
bar. This patch adds support to trigger the conflict and data leds with
the packages.

arcnet: com20020: replace magic numbers with readable macros

2015-09-23T06:44:28+00:00

This patch replaces all magic numbers in the driver with
proper named macros. For the case of XTOcfg and STARTIOcmd
it introduces the new macros.

arcnet: Remove unused arcnet_w macros

2015-09-23T06:44:28+00:00

The word length macros are unused. Remove them. Signed-off-by: Joe Perches Signed-off-by: Michael Grzeschik

arcnet: Remove function pointer macro indirections

2015-09-23T06:44:27+00:00

It's clearer to use function pointer calls directly instead of the macro indirections of ARCRESET, ACOMMAND, ASTATUS, and AINTMASK. Remove the now unused macros too. Signed-off-by: Joe Perches Signed-off-by: Michael Grzeschik

arcnet: arcdevice.h: Add arcnet_readb and arcnet_writeb

2015-09-23T06:44:27+00:00

Use the same indirection as the other arcnet_ macros. Neither of these new macros add the BUS_ALIGN use for 8 bit devices on 16 bit busses. Signed-off-by: Joe Perches Signed-off-by: Michael Grzeschik

arcnet: com20020: Use arcnet_ routines

2015-09-23T06:44:26+00:00

Simplify and make consistent the current uses of inb/outb by using the newly introduced arcnet_ equivalents. o Add new #defines for register offsets There is an register offset, 8, that is unnamed and used as-is. o Remove old #defines that included the ioaddr o Remove obfuscating macros by expanding them in-place where appropriate o Create static inline com20020_set_subaddress for the SET_SUBADR macro There is an unused arcnet config entry CONFIGSA100_CT6001 which added a special #define BUS_ALIGN which was introduced but never used in fullhist git tree commit 22cfce4b82b0 ("[ARCNET]: Fixes.") in Nov 2004 for Linux v2.6.10. This BUS_ALIGN #define tries to allow 8 bit devices to work on a 16 bit bus by aligning addresses to 16 bit boundaries. Move this currently unused CONFIG_SA1100_CT6001 BUS_ALIGN macro from com20020.h to arcdevice.h. Signed-off-by: Joe Perches Signed-off-by: Michael Grzeschik

arcnet: Add arcnet_ macros

2015-09-23T06:44:26+00:00

arcnet uses an I/O scheme which can align I/O addresses to word boundaries on different architectures. Add arcnet specific macros which can hide this alignment calculation. Signed-off-by: Joe Perches Signed-off-by: Michael Grzeschik
