When handling large number of netdevice, rtnl_dump_ifinfo() is very slow because it has O(N^2) complexity. Instead of scanning one single list, we can use the 256 sub lists of the dev_index hash table. This considerably speedups "ip link" operations Signed-off-by:

GRE tunnels use one rwlock to protect their hash tables. This locking scheme can be converted to RCU for free, since netdevice already must wait for a RCU grace period at dismantle time. Signed-off-by:

SIT tunnels use one rwlock to protect their prl entries. This first patch adds RCU locking for prl management, with standard call_rcu() calls. Signed-off-by:

The 'XFP' driver is really a driver for the QT2022C2 and QT2025C PHYs, covering both more and less than XFP. Rename its functions and constants to reflect reality and to reduce namespace pollution when sfc is a built-in driver. Signed-off-by:

The only multi-speed PHY driver using this is 10Xpress, and it does not support non-autoneg operation. Signed-off-by:

efx_fc_resolve() is specific to MDIO and is not used by any other function. Signed-off-by:

The MTD partition is named based on the netdev name, which is set to 'eth%d' before registration. Also, the MTD partition will currently be left registered if netdev registration fails. Fix both these problems by moving the MTD probe after netdev registration. Hold the RTNL to serialise this with the netdev notifier that calls efx_mtd_rename(). Signed-off-by:

MAC and PHY probing are bound up together, as evidenced by the initialisation of efx_nic::loopback_modes. Remove the current arbitrary separation. Signed-off-by:

This makes efx_pci_remove_main() more obviously the inverse of efx_pci_probe_main(), and matches our out-of-tree driver. Signed-off-by:

Replace the duplicated logic in efx_enqueue_skb() and efx_tx_queue_insert() with an inline function, efx_max_tx_len(). Remove the failed attempt at abstracting hardware-specifics and put all the magic numbers in efx_max_tx_len(). Signed-off-by:

Siena is still based on the Falcon hardware architecture and will share many of these definitions, so replace falcon_hwdefs.h with regs.h. The new definitions have been generated according to a naming convention which incorporates the type and revision information. Update the code accordingly. Signed-off-by:

Since there are now separate blocks of code to set the thresholds for each NIC type, it is no longer useful to include them in the NIC type description. Signed-off-by:

These macros are not extensible to more than two NIC types without repetition of register definitions, and they are only used to deal with a few fields in RX_CFG_REG and global events which moved between Falcon rev A1 and B0. Therefore: - Move RX_CFG_REG initialisation into its own function which tests the NIC revision just once - Explicitly test the NIC revision when checking the RX_RECOVERY flag in global events - Merge definitions of RX_XOFF_MAC_EN flag, which did not move - Remove the macro definitions Signed-off-by:

Commits 27fbc7db 'mdio: Expose pause frame advertising flags to ethtool' and c634263d 'sfc: 10Xpress: Initialise pause advertising flags' added to our reported advertising flags. efx_mdio_set_settings() requires that all advertising flags are also present in the supported flags, so make sure that is true.

rtnl_getlink() & rtnl_setlink() run with RTNL held, we can use __dev_get_by_index() and __dev_get_by_name() variants and avoid dev_hold()/dev_put() Adds to rtnl_getlink() the capability to find a device by its name, not only by its index. Signed-off-by:
