The watchdog will not trigger when the carrier is off when reconfiguring the device. Because carrier state is now off during reset, we need to introduce a link_up flag to keep track of link state during PHY setup. Signed-off-by:

- Also refactor the conditional to use the existing tg3_pci_tbl array. - Set flags in the driver_data field of the pci_device_id structure to identify these devices. - Add PCI_DEVICE_SUB() to pci.h to declare PCI 4-part IDs to match these devices. Signed-off-by:

netdev_state_change() was called only when end points or link was updated. Now that all parameters are advertised via netlink, we must advertise any change. This patch also prepares the support of sit tunnels management via rtnl. The code which update tunnels will be put in a new function. Signed-off-by:

This is Linux bridge implementation of root port guard. If BPDU is received from a leaf (edge) port, it should not be elected as root port. Why would you want to do this? If using STP on a bridge and the downstream bridges are not fully trusted; this prevents a hostile guest for rerouting traffic. Why not just use netfilter? Netfilter does not track of follow spanning tree decisions. It would be difficult and error prone to try and mirror STP resolution in netfilter module. Signed-off-by:

This is Linux bridge implementation of STP protection (Cisco BPDU guard/Juniper BPDU block). BPDU block disables the bridge port if a STP BPDU packet is received. Why would you want to do this? If running Spanning Tree on bridge, hostile devices on the network may send BPDU and cause network failure. Enabling bpdu block will detect and stop this. How to recover the port? The port will be restarted if link is brought down, or removed and reattached. For example: # ip li set dev eth0 down; ip li set dev eth0 up Signed-off-by:

Expose bridge port parameter over netlink. By switching to a nested message, this can be used for other bridge parameters. This changes IFLA_PROTINFO attribute from one byte to a full nested set of attributes. This is safe for application interface because the old message used IFLA_PROTINFO and new one uses IFLA_PROTINFO | NLA_F_NESTED. The code adapts to old format requests, and therefore stays compatible with user mode RSTP daemon. Since the type field for nested and unnested attributes are different, and the old code in libnetlink doesn't do the mask, it is also safe to use with old versions of bridge monitor command. Note: although mode is only a boolean, treating it as a full byte since in the future someone will probably want to add more values (like macvlan has). Signed-off-by:

Only the first register set is used for matching but we support getting the initial hw addr from any of the registers. To prevent stale entries and false matches clear unused register sets. This most important for the at91_ether driver where u-boot always uses the 2nd register set. Signed-off-by:

This change is meant to both improve the performance and reduce the size of igb_tx_map. To do this I have expanded the work done in the main loop by pushing first into tx_buffer. This allows us to pull in the dma_mapping_error check, the tx_buffer value assignment, and the initial DMA value assignment to the Tx descriptor. The net result is that the function reduces in size by a little over a 100 bytes and is about 1% or 2% faster. Signed-off-by:

This change is meant to improve the efficiency of the Tx flags in igb by aligning them with the values that will later be written into either the cmd_type or olinfo. By doing this we are able to reduce most of these functions to either just a simple shift followed by an or in the case of cmd_type, or an and followed by an or in the case of olinfo. In order to avoid type conversion errors I also adjusted the locations where we were switching between CPU and little endian. Signed-off-by:

This change is meant to reduce the overhead for workloads that are not using either TSO or checksum offloads. Most of the time the compiler should jump ahead after failing this check to the VLAN check since in the igb_tx_csum call we start with that check as well. Signed-off-by:

napi_gro_receive shouldn't be called from netpoll context. Doing so was causing kernel panics when jumbo frames larger than 2K were set.

The way the code was previously written it was causing DCA to prefetch the entire packet into the cache when it was enabled. That is excessive as we only really need the headers. We are now prefetching the headers via software so doing this from DCA would be redundant anyway. So clear the bit that was causing us to prefetch the packet data and instead only use DCA for the descriptor rings. Signed-off-by:
