2013-04-19net: vlan: prepare for 802.1ad VLAN filtering offloadPatrick McHardy1-4/+2
Change the rx_{add,kill}_vid callbacks to take a protocol argument in preparation of 802.1ad support. The protocol argument used so far is always htons(ETH_P_8021Q). Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-04-19net: vlan: rename NETIF_F_HW_VLAN_* feature flags to NETIF_F_HW_VLAN_CTAG_*Patrick McHardy1-2/+2
Rename the hardware VLAN acceleration features to include "CTAG" to indicate that they only support CTAGs. Follow up patches will introduce 802.1ad server provider tagging (STAGs) and require the distinction for hardware not supporting acclerating both.

2012-12-11bna: Firmware updateRasesh Mody3-2/+4
Change Details: - Added Stats clear counter to the bfi_enet_stats_mac structure and ethtool stats - Modified the firmware naming convention to contain the firmware image version (3.1.0.0). The new convention is <firmware-image>-<firmware-version>.bin The change will enforce loading only compatible firmware with this driver and also avoid over-writing the old firmware image in-order to load new version driver as the firmware names used to be the same.

2012-12-11bna: Add RX StateRasesh Mody1-1/+26
Change Details: - BNA state machine for Rx in start_wait state moves it to stop_wait on receipt of RX_E_STOP. In Rx stop_wait state, on receipt of RX_E_STARTED event does enet stop RX_E_STOPPED event does rx_cleanup_cbfn rx_cleanup_cbfn in this case is called without post_cbfn. post_cbfn happens only after RX_E_STARTED event is received in start_wait. Without doing post_cbfn, NAPI remains disabled and in cleanup we try to disable again causing endless wait. ifconfig process and other workers can thus get stuck. - Introducing start_stop_wait state for Rx. This state handles the case of if post_cbfn is not done simply do stop without the cleanup. Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Adding casts of objects to the same type is unnecessary and confusing for a human reader.

This patch removes busy wait in tx/rx cleanup. bnad_cb_tx_cleanup() and bnad_cb_rx_cleanup() functions are called from irq context, and currently they do busy wait for the in-flight transmit or the currently executing napi polling routine to complete.
