Implements the dcbnl netlink setapp/getapp pair. When a setapp/getapp is received, dcbnl would just pass on to dcbnl_rtnl_op.setapp/getapp that are supposed to be implemented by the low level drivers. Signed-off-by:

Adds support of dcbnl setapp/getapp to dcbnl_rtnl_ops in netdev to allow LLDs to implement their corresponding dcbnl setapp/getapp ops to support the IEEE 802.1Q DCBX setapp/getapp commands. Signed-off-by:

This patch adds dcbnl command definitions to support setapp/getapp functionality from the IEEE 802.1Qaz Data Center Bridging Capability Exchange protocol (DCBX) specification. Section 3.3 defines the application protocol and its 802.1p user priority in DCBX, which is implemented here as a pair of setapp/getapp commands in the kernel dcbnl for setting and retrieving the user priority for an given application protocol. The protocol is identified by the combination of an id and an idtype. Currently, when idtype is 0, the corresponding id gives the ether type of this protocol, e.g., for FCoE, it will be 0x8906; when idtype is 1, then the corresponding id gives the TCP or UDP port number. For more information regarding DCBX spec., please refer to the following: http://www.ieee802.org/1/files/public/docs2008/ az-wadekar-dcbx-capability-exchange-discovery-protocol-1108-v1.01.pdf Signed-off-by:

This adds support to the net_device_ops.ndo_fcoe_enable/disable for 82599. This consequently allows us to dynamically turn FCoE offload feature on or off upon incoming calls to ndo_fcoe_enable/disable. When this happens, FCoE offload features are enabled/disabled accordingly, and this is regardless of whether DCB being turned on or not. Signed-off-by:

This adds implementation of the net_devices_ops.ndo_fcoe_enable/_disable to the VLAN driver. It checks if the real_dev has support for ndo_fcoe_enable/ ndo_fcoe_disable and if so, passes on to call the associated real_dev. Signed-off-by:

Add ndo_fcoe_enable/_disable to net_device_ops so the corresponding HW can initialize itself for FCoE traffic or clean up after FCoE traffic is done. This is expected to be called by the kernel FCoE stack upon receiving a request for creating an FCoE instance on the corresponding netdev interface. When implemented by the actual HW, the HW driver check the op code to perform corresponding initialization or clean up for FCoE. The initialization normally includes allocating extra queues for FCoE, setting corresponding HW registers for FCoE, indicating FCoE offload features via netdev, etc. The clean-up would include releasing the resources allocated for FCoE.

Mostly just simple conversions: * ray_cs had bogus return of NET_TX_LOCKED but driver was not using NETIF_F_LLTX * hostap and ipw2x00 had some code that returned value from a called function that also had to change to return netdev_tx_t Signed-off-by: -

The transmit function should only return one of three possible values, some drivers got confused and returned errno's or other values. This changes the definition so that this can be caught at compile time. Signed-off-by:

Single line log messages should be emitted by a single call where possible. Converted multiple calls to DBG_PRINT to single call form. Removed "s2io:" preface from DBG_PRINTs. The DBG_PRINT macro now emits a log level and is surrounded by a do {...} while (0) All s2io log output is now prefaced with KBUILD_MODNAME ": " via pr_fmt. The DBG_PRINT macro should probably be converted to use the dev_<level> form eventually. Signed-off-by:Joe Perches <joe@perches.com> Acked-by:

Regularize the declaration and uses of struct config_param *config = &sp->config; struct mac_info *mac_control = &sp->mac_control; and use struct stat_block *stats = mac_control->stats_info; struct swStat *swstats = &stats->sw_stat; struct xpakStat *xstats = &stats->xpak_stat; and convert the longish uses like nic->mac_control.stats_info->sw_stat.<foo> to swstats-><foo> etc. This also makes the statistics code marginally smaller and presumably faster.

Repeated variable use and line wrapping is hard to read. Use temp variables instead of direct references. struct fifo_info *fifo = &mac_control->fifos[i]; struct ring_info *ring = &mac_control->rings[i]; struct tx_fifo_config *tx_cfg = &config->tx_cfg[i]; struct rx_ring_config *rx_cfg = &config->rx_cfg[i]; Signed-off-by:

pfifo_fast_enqueue has this check: if (skb_queue_len(list) < qdisc_dev(qdisc)->tx_queue_len) { which allows each band to enqueue upto tx_queue_len skbs for a total of 3*tx_queue_len skbs. I am not sure if this was the intention of limiting in qdisc. Patch compiled and 32 simultaneous netperf testing ran fine. Also: # tc -s qdisc show dev eth2 qdisc pfifo_fast 0: root bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 Sent 16835026752 bytes 373116 pkt (dropped 0, overlimits 0 requeues 25) rate 0bit 0pps backlog 0b 0p requeues 25 Signed-off-by:Krishna Kumar <krkumar2@in.ibm.com> Signed-off-by:
