net: arc_emac: prevent reuse of unreclaimed tx descriptors

2014-09-12T21:18:03Z

This patch changes the logic in tx path to ensure that tx descriptors are reused for transmission only after they have been reclaimed by arc_emac_tx_clean(). Signed-off-by: Beniamino Galvani Signed-off-by: David S. Miller

net: arc_emac: enable tx interrupts

2014-09-12T21:17:49Z

In the current implementation the cleaning of tx ring is done by the NAPI poll handler, which is scheduled after rx interrupts. Thus, in absence of received packets the reclaim of used tx buffers is never executed, blocking further transmission. This can be easily reproduced starting the transmission of a UDP flow with iperf, which blocks almost immediately because skbs are not returned to the stack and the socket send buffer becomes full. The patch enables tx interrupts so that the tx reclaim is scheduled after completed transmissions. Signed-off-by: Beniamino Galvani Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

arc_emac: Remove unused pointer to net_device from arc_emac_priv

2014-07-09T23:49:21Z

The pointer to the struct net_device in the private data is only assigned but never used, so delete it. Signed-off-by: Tobias Klauser Signed-off-by: David S. Miller

arc_emac: Use net_device_stats from struct net_device

2014-07-09T23:48:35Z

Instead of using a private copy of struct net_device_stats in struct arc_emac_priv, use stats from struct net_device. Signed-off-by: Tobias Klauser Signed-off-by: David S. Miller

arc_emac: implement promiscuous mode and multicast filtering

2014-05-13T22:02:24Z

This patch implements the set_rx_mode function to enable/disable promiscuous or all-multicast modes and to update the multicast filtering list of the device. Signed-off-by: Beniamino Galvani Signed-off-by: David S. Miller

arc_emac: add clock handling

2014-04-27T23:46:17Z

This adds ability for the arc_emac to really handle its supplying clock. To get the needed clock-frequency either a real clock or the previous clock-frequency property must be provided. Signed-off-by: Heiko Stuebner Tested-by: Max Schwarz Signed-off-by: David S. Miller

arc_emac: fix probe error path

2014-04-27T23:46:17Z

The probe function at the moment only frees the netdev but does not disconnect the phy or removes the mdio bus it registered. Signed-off-by: Heiko Stuebner Signed-off-by: David S. Miller

arc_emac: write initial MAC address from devicetree to hw

2014-04-22T19:55:11Z

The MAC address retrieved from dt was not actually written to the hardware. This meant proper communication was only possible after changing the MAC address. Fix that by always writing the mac address during probing. Signed-off-by: Max Schwarz Acked-by: Heiko Stuebner Tested-by: Heiko Stuebner Signed-off-by: David S. Miller
