- Defer dellink to net_cleanup() allowing for batching. - Fix comment. - Use for_each_netdev_safe again as dev_change_net_namespace touches at most one network device (unlike veth dellink). Signed-off-by:

Defer calling unregister_netdevice_queue to cleanup_net. It's simpler and it allows the loopback device to land in the same batch as other network devices. Signed-off-by:

To get the full benefit of batched network namespace cleanup netowrk device deletion needs to be performed by the generic code. When using register_pernet_gen_device and freeing the data in exit_net it is impossible to delay allocation until after exit_net has called as the device uninit methods are no longer safe. To correct this, and to simplify working with per network namespace data I have moved allocation and deletion of per network namespace data into the network namespace core. The core now frees the data only after all of the network namespace exit routines have run. Now it is only required to set the new fields .id and .size in the pernet_operations structure if you want network namespace data to be managed for you automatically. This makes the current register_pernet_gen_device and register_pernet_gen_subsys routines unnecessary. For the moment I have left them as compatibility wrappers in net_namespace.h They will be removed once all of the users have been updated. Signed-off-by:

It is fairly common to kill several network namespaces at once. Either because they are nested one inside the other or because they are cooperating in multiple machine networking experiments. As the network stack control logic does not parallelize easily batch up multiple network namespaces existing together. To get the full benefit of batching the virtual network devices to be removed must be all removed in one batch. For that purpose I have added a loop after the last network device operations have run that batches up all remaining network devices and deletes them. An extra benefit is that the reorganization slightly shrinks the size of the per network namespace data structures replaceing a work_struct with a list_head. In a trivial test with 4K namespaces this change reduced the cost of a destroying 4K namespaces from 7+ minutes (at 12% cpu) to 44 seconds (at 60% cpu). The bulk of that 44s was spent in inet_twsk_purge. Signed-off-by:

I will need this shortly to implement network namespace shutdown batching. For sanity sake network devices should be removed in the reverse order they were created in. Signed-off-by:

The motivation for an additional notifier in batched netdevice notification (rt_do_flush) only needs to be called once per batch not once per namespace. For further batching improvements I need a guarantee that the netdevices are unregistered in order allowing me to unregister an all of the network devices in a network namespace at the same time with the guarantee that the loopback device is really and truly unregistered last. Additionally it appears that we moved the route cache flush after the final synchronize_net, which seems wrong and there was no explanation. So I have restored the original location of the final synchronize_net. Cc: Octavian Purdila <opurdila@ixiacom.com> Signed-off-by:

This adds support for the SFC9000 family of 10G Ethernet controllers and LAN-on-motherboard chips, starting with the SFL9021 'Siena' and SFC9020 'Bethpage'. The SFC9000 family is based on the SFC4000 'Falcon' architecture, but with some significant changes: - Two ports are associated with two independent PCI functions (except SFC9010) - Integrated 10GBASE-T PHY(s) (SFL9021/9022) - MAC, PHY and board peripherals are managed by firmware - Driver does not require board-specific code - Firmware supports wake-on-LAN and lights-out management through NC-SI - IPv6 checksum offload and RSS - Filtering by MAC address and VLAN (not included in this code) - PCI SR-IOV (not included in this code) Credit for this code is largely due to my colleagues at Solarflare: Guido Barzini Steve Hodgson Kieran Mansley Matthew Slattery Neil Turton Signed-off-by:

In new NICs flash is managed by firmware and we will use high-level operations on partitions rather than direct SPI commands. Add support for multiple MTD partitions per flash device and remove the direct link between MTD and SPI devices. Maintain a list of MTD partitions in struct efx_nic. Signed-off-by:

Refactor PHY, MAC and NIC configuration operations so that the existing link configuration can be re-pushed with: efx->phy_op->reconfigure(efx); efx->mac_op->reconfigure(efx); and a new configuration with: efx->nic_op->reconfigure_port(efx); (plus locking and error-checking). We have not held the link settings in software (aside from flow control), and have relied on asking the hardware what they are. This is a problem because in some cases the hardware may no longer be in a state to tell us. In particular, if an entire multi-port board is reset through one port, the driver bindings to other ports have no chance to save settings before recovering. We only actually need to keep track of the autonegotiation settings, so add an ethtool advertising mask to struct efx_nic, initialise it in PHY init and update it as necessary. Remove now-unneeded uses of efx_phy_op::{get,set}_settings() and struct ethtool_cmd. Much of this was done by Steve Hodgson <shodgson@solarflare.com>. Signed-off-by: -

Pause frame generation is gated by both RX_XOFF_MAC_EN and an enable bit in each MAC. RX_XOFF_MAC_EN bit always reads back as 0 so we need to set it correctly every time we modify RX_CFG_REG. Simplify this by always setting it to 1 and only changing the enable bits in the MACs. Signed-off-by:
