When VLAN filtering is enabled on a bridge and PVID is deleted from a bridge port, then untagged frames are not allowed to ingress into the bridge from this port. Add the Switch Port Acceptable Frame Types (SPAFT) register, which configures the frame admittance of the port.

With commit 0071f56e ("dsa: Register netdev before phy"), we are now trying to free a network device that has been previously registered, and in case of errors, this will make us hit the BUG_ON(dev->reg_state != NETREG_UNREGISTERED) condition.

For the Marvell 88E1510, marvell_of_reg_init was called too late, in the config_aneg function. Since commit 113c74d8 ("net: phy: turn carrier off on phy attach"), this lead to the link not coming up at boot anymore, due to the phy state machine being stuck at waiting for interrupts (off by default on the 88E1510). For seven other Marvell PHYs, marvell_of_reg_init was not called at all. Add a generic marvell_config_init function, which in turn calls marvell_of_reg_init. PHYs, which already have a specific config_init function with a call to marvell_of_reg_init, are left untouched. The generic marvell_config_init function is called for all the others, to get consistent behavior across all Marvell PHYs. Fixes: 113c74d8 ("net: phy: turn carrier off on phy attach") Signed-off-by:

When a VLAN device leaves a bridge its STP state is set to DISABLED, which causes the hardware to discard any packets coming through the port with this VLAN.

A previous commit (33f72e6f) added notification via netlink for tunnels when created/modified/deleted. If the notification returned an error, this error was returned from the tunnel function. If there were no listeners, the error code ESRCH was returned, even though having no listeners is not an error. Other calls to this and other similar notification functions either ignore the error code, or filter ESRCH. This patch checks for ESRCH and does not flag this as an error. Reviewed-by:

The cpsw-phy-sel driver supports only MII, RMII, and RGMII PHY modes, and silently handled any other values as if MII was specified. In a case where the PHY mode was incorrectly specified, or a bug elsewhere, there would be no indication of a problem. If MII was the correct mode, then this will go unnoticed, otherwise the symptom will be a failure to transmit/receive data over the RMII/RGMII link. Add a dev_warn() to make this condition obvious and provide a breadcrumb to follow. Cc: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by:

It's forbidden to manually change dev->features in run-time. Currently, this is done in the driver to make sure that GSO_UDP_TUNNEL is advertized only when VXLAN tunnel is set. However, since the stack actually does features intersection with hw_enc_features, we can safely revert to advertizing features early when registering the netdevice.

problem description: The current code sets UAR page size equal to system page size. The ConnectX-3 and ConnectX-3 Pro HWs require minimum 128 UAR pages. The mlx4 kernel drivers are not loaded if there is less than 128 UAR pages. solution: Always set UAR page to 4KB. This allows more UAR pages if the OS has PAGE_SIZE larger than 4KB. For example, PowerPC kernel use 64KB system page size, with 4MB uar region, there are 4MB/2/64KB = 32 uars (half for uar, half for blueflame). This does not meet minimum 128 UAR pages requirement. With 4KB UAR page, there are 4MB/2/4KB = 512 uars which meet the minimum requirement. Note that only codes in mlx4_core that deal with firmware know that uar page size is 4KB. Codes that deal with usr page in cq and qp context (mlx4_ib, mlx4_en and part of mlx4_core) still have the same assumption that uar page size equals to system page size. Note that with this implementation, on 64KB system page size kernel, there are 16 uars per system page but only one uars is used. The other 15 uars are ignored because of the above assumption. Regarding SR-IOV, mlx4_core in hypervisor will set the uar page size to 4KB and mlx4_core code in virtual OS will obtain the uar page size from firmware. Regarding backward compatibility in SR-IOV, if hypervisor has this new code, the virtual OS must be updated. If hypervisor has old code, and the virtual OS has this new code, the new code will be backward compatible with the old code. If the uar size is big enough, this new code in VF continues to work with 64 KB uar page size (on PowerPc kernel). If the uar size does not meet 128 uars requirement, this new code not loaded in VF and print the same error message as the old code in Hypervisor. Signed-off-by:

Previously, the shift value used for time-stamping was constant and didn't depend on the HW chip frequency. Change that to take the frequency into account and calculate the maximal value in cycles per wraparound of ten seconds. This time slot was chosen since it gives a good accuracy in time synchronization. Algorithm for shift value calculation: * Round up the maximal value in cycles to nearest power of two * Calculate maximal multiplier by division of all 64 bits set to above result * Then, invert the function clocksource_khz2mult() to get the shift from maximal mult value Fixes: ec693d47 ('net/mlx4_en: Add HW timestamping (TS) support') Signed-off-by:

In commit 52666986 ("tipc: let broadcast packet reception use new link receive function") we introduced a new per-node broadcast reception link instance. This link is created at the moment the node itself is created. Unfortunately, the allocation is done after the node instance has already been added to the node lookup hash table. This creates a potential race condition, where arriving broadcast packets are able to find and access the node before it has been fully initialized, and before the above mentioned link has been created. The result is occasional crashes in the function tipc_bcast_rcv(), which is trying to access the not-yet existing link. We fix this by deferring the addition of the node instance until after it has been fully initialized in the function tipc_node_create(). Acked-by:

The push buffer has to be zero padded to the next 64-bit word boundary or tx checksum won't be correct. 3. Increase the tx push packet threshold to 164 bytes (192 bytes with the BD) so that small tunneled packets are within the threshold. Signed-off-by:
