We currently use a 16 bit field (vlan_tci) to store VLAN ID/PRIO on a skb. Null value is used as a special value, meaning vlan tagging not enabled. This forbids use of null vlan ID. As pointed by David, some drivers use the 3 high order bits (PRIO) As VLAN ID is 12 bits, we can use the remaining bit (CFI) as a flag, and allow null VLAN ID. In case future code really wants to use VLAN_CFI_MASK, we'll have to use a bit outside of vlan_tci. #define VLAN_PRIO_MASK 0xe000 /* Priority Code Point */ #define VLAN_PRIO_SHIFT 13 #define VLAN_CFI_MASK 0x1000 /* Canonical Format Indicator */ #define VLAN_TAG_PRESENT VLAN_CFI_MASK #define VLAN_VID_MASK 0x0fff /* VLAN Identifier */ Reported-by:

Commit 7b6856a0 "can: provide library functions for skb allocation" did not properly remove two lines of the SJA1000 driver resulting in a 'skb_over_panic' when calling skb_put, as reported by Kurt. Signed-off-by:

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:

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 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:

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:

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:

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:
