When running vlan test (bridge_vlan_aware/unaware.sh), there were some failure due to the lack .port_bridge_flag function to disable port flooding. Implement this operation for BR_LEARNING, BR_FLOOD, BR_MCAST_FLOOD and BR_BCAST_FLOOD. Since .port_bridge_flags affects the bits disabling learning for a port, ensure that any other modification on the same register done by a5psw_port_stp_state_set is in sync by using the port learning state to enable/disable learning on the port.

.port_bridge_flags will be added and allows to modify the flood mask independently for each port. Keeping the existing bridged_ports write in a5psw_flooding_set_resolution() would potentially messed up this. Use a read-modify-write to set that value and move bridged_ports handling in bridge_port_join/leave. Signed-off-by:

The current implementation does not allow the user to enable both hw-tc-offload and ntuple features on the interface. These checks are added as TC flower offload and ntuple features internally configures the same hardware resource MCAM. But TC HTB offload configures the transmit scheduler which can be safely enabled on the interface with ntuple feature. This patch adds the same and ensures only TC flower offload and ntuple features are mutually exclusive. Signed-off-by:

In bond_reset_slave_arr(), values are assigned and memory is released only when the variables "usable" and "all" are not NULL. But even if the "usable" and "all" variables are NULL, they can still work, because value will be checked in kfree_rcu. Therefore, use bond_set_slave_arr() and set the input parameters "usable_slaves" and "all_slaves" to NULL to simplify the code in bond_reset_slave_arr(). And the same to bond_uninit(). Signed-off-by:

When gso.hdr_len is zero and a packet is transmitted via write() or writev(), all payload is treated as header which requires a contiguous memory allocation. This allocation request is harder to satisfy, and may even fail if there is enough fragmentation. Note that sendmsg() code path limits the linear copy length, so this change makes write()/writev() and sendmsg() paths more consistent. Signed-off-by:

Linux LEDs can be requested to perform hardware accelerated blinking to indicate link, RX, TX etc. Pass the rules for blinking to the PHY driver, if it implements the ops needed to determine if a given pattern can be offloaded, to offload it, and what the current offload is. Additionally implement the op needed to get what device the LED is for. Reviewed-by:

When the netdev trigger is activates, it tries to determine what device the LED blinks for, and what the current blink mode is. The documentation for hw_control_get() says: * Return 0 on success, a negative error number on failing parsing the * initial mode. Error from this function is NOT FATAL as the device * may be in a not supported initial state by the attached LED trigger. */ For the Marvell PHY and the Armada 370-rd board, the initial LED blink mode is not supported by the trigger, so it returns an error. This resulted in not getting the device the LED is blinking for. As a result, the device is unknown and offloaded is never performed. Change to condition to always get the device if offloading is supported, and reduce the scope of testing for an error from hw_control_get() to skip setting trigger internal state if there is an error.

Shenwei Wang authored
When using a fixed-link setup, certain devices like the SJA1105 require a small pause in the TXC clock line to enable their internal tunable delay line (TDL). To satisfy this requirement, this patch temporarily disables the TX clock, and restarts it after a required period. This provides the required silent interval on the clock line for SJA1105 to complete the frequency transition and enable the internal TDLs. This action occurs before the link is built up, so it does not impact a normal device too. There is no need to identify if the connected device is an SJA1105 alike or not during the implementation. So far we have only enabled this feature on the i.MX93 platform. Signed-off-by:

We used to change the flags for the last segment, because non-last segments had the MSG_SENDPAGE_NOTLAST flag set. That flag is no longer a thing so remove the setting. Since flags most likely don't have MSG_SPLICE_PAGES set this avoids passing parts of the sg as splice and parts as non-splice. Before commit under Fixes we'd have called tcp_sendpage() which would add the MSG_SPLICE_PAGES. Why this leads to trouble remains unclear but Tariq reports hitting the WARN_ON(!sendpage_ok()) due to page refcount of 0. Fixes: e117dcfd ("tls: Inline do_tcp_sendpages()") Reported-by:
