Igor Russkikh says: ==================== net: atlantic: phy tunables from mac driver This series implements phy tunables settings via MAC driver callbacks. AQC 10G devices use integrated MAC+PHY solution, where PHY is fully controlled by MAC firmware. Therefore, it is not possible to implement separate phy driver for these.

Mediadetect is another name for the EDPD (energy detect power down). This feature allows device to save extra power when no link is available. PHY goes into the extreme power saving mode and only periodically wakes up and checks for the link. AQC devices has fixed check period of 6 seconds The feature may increase linkup time.

A driver may refuse to enable VLAN filtering for any reason beyond what the DSA framework cares about, such as: - having tc-flower rules that rely on the switch being VLAN-aware - the particular switch does not support VLAN, even if the driver does (the DSA framework just checks for the presence of the .port_vlan_add and .port_vlan_del pointers) - simply not supporting this configuration to be toggled at runtime Currently, when a driver rejects a configuration it cannot support, it does this from the commit phase, which triggers various warnings in switchdev. So propagate the prepare phase to drivers, to give them the ability to refuse invalid configurations cleanly and avoid the warnings. Since we need to modify all function prototypes and check for the prepare phase from within the drivers, take that opportunity and move the existing driver restrictions within the prepare phase where that is possible and easy.

1. Keep the code for the normal (non-error) flow at the lowest indentation level. And use "goto drop" for all error handling. 2. Replace code that pads short Ethernet frames with a "__skb_pad" call. 3. Change "dev_kfree_skb" to "kfree_skb" in error handling code. "kfree_skb" is the correct function to call when dropping an skb due to an error. "dev_kfree_skb", which is an alias of "consume_skb", is for dropping skbs normally (not due to an error).

Openvswitch allows to drop a packet's Ethernet header, therefore skb_mpls_push() and skb_mpls_pop() might be called with ethernet=true and mac_len=0. In that case the pointer passed to skb_mod_eth_type() doesn't point to an Ethernet header and the new Ethertype is written at unexpected locations. Fix this by verifying that mac_len is big enough to contain an Ethernet header. Fixes: fa4e0f88 ("net/sched: fix corrupted L2 header with MPLS 'push' and 'pop' actions") Signed-off-by:

The variable "i" isn't initialized back correctly after the first loop under the label inst_rollback gets executed. The value of "i" is assigned to be option_count - 1, and the ensuing loop (under alloc_rollback) begins by initializing i--. Thus, the value of i when the loop begins execution will now become i = option_count - 2. Thus, when kfree(dst_opts[i]) is called in the second loop in this order, (i.e., inst_rollback followed by alloc_rollback), dst_optsp[option_count - 2] is the first element freed, and dst_opts[option_count - 1] does not get freed, and thus, a memory leak is caused. This memory leak can be fixed, by assigning i = option_count (instead of option_count - 1).

Michael Chan says: ==================== bnxt_en: net-next updates. This series starts off with the usual update of the firmware interface spec. A new firmware status bit in the interface will be used in patch add the infrastructure to read the firmware status very early during driver probe and this will allow patch #4 to do the recovery if needed. The rest of the patches add improvements to the current RX reset logic by localizing the reset to the affected RX ring only and to reset only if firmware has determined that the RX ring is in permanent error state. ==================== Signed-off-by: -
Michael Chan authored
Currently, the driver will schedule RX ring reset when we get a buffer error in the RX completion record. These RX buffer errors can be due to normal out-of-buffer conditions or a permanent error in the RX ring. Because the driver cannot distinguish between these 2 conditions, we assume all these buffer errors require reset. This is very disruptive when it is just a normal out-of-buffer condition. Newer firmware will now monitor the rings for the permanent failure and will send a notification to the driver when it happens. This allows the driver to reset only when such a notification is received. In environments where we have predominently out-of-buffer conditions, we now can avoid these unnecessary resets.

There is logic in the RX path to detect unexpected handles in the RX completion. We'll print a warning and schedule a reset. The next expected handle is then set to 0xffff which is guaranteed to not match any valid handle. This will force all remaining packets in the ring to be discarded before the reset. There can be hundreds of these packets remaining in the ring and there is no need to print the warnings for these forced errors. Reviewed-by:

Michael Chan authored
On some older chips, it is necessary to do a reset when we get buffer errors associated with an RX ring. These buffer errors may become frequent if the RX ring underruns under heavy traffic. The current code does a global reset of all reasources when this happens. This works but creates a big disruption of all rings when one RX ring is having problem. This patch implements a localized RX ring reset of just the RX ring having the issue. All other rings including all TX rings will not be affected by this single RX ring reset. Only the older chips prior to the P5 class supports this reset. Because it is not a global reset, packets may still be arriving while we are calling firmware to reset that ring. We need to be sure that we don't post any buffers during this time while the ring is undergoing reset. After firmware completes successfully, the ring will be in the reset state with no buffers and we can start filling it with new buffers and posting them. Reviewed-by:

bnxt_init_one_rx_ring() includes logic to initialize the BDs for one RX ring and to allocate the buffers. Separate the allocation logic into a new bnxt_alloc_one_rx_ring() function. The allocation function will be used later to allocate new buffers for one specified RX ring when we reset that RX ring. Reviewed-by:

bnxt_free_rx_skbs() frees all the allocated buffers and SKBs for every RX ring. Refactor this function by calling a new function bnxt_free_one_rx_ring_skbs() to free these buffers on one specified RX ring at a time. This is preparation work for resetting one RX ring during run-time. Reviewed-by:

The NS3 SoC platforms require assistance from the OP-TEE to recover firmware if a crash occurs while no driver is bound. The CRASHED_NO_MASTER condition is recorded in the firmware status register during the crash to indicate when driver intervension is needed to coordinate a firmware reload. This condition is detected during early driver initialization in order to effect a firmware fastboot on supported platforms when necessary. Reviewed-by:
