2024-09-04pds_core: Remove redundant null pointer checksLi Zetao
Since the debugfs_create_dir() never returns a null pointer, checking the return value for a null pointer is redundant, and using IS_ERR is safe enough.

2024-09-04net: mana: Improve mana_set_channels() in low mem conditionsShradha Gupta
The mana_set_channels() function requires detaching the mana driver and reattaching it with changed channel values. During this operation if the system is low on memory, the reattach might fail, causing the network device being down. To avoid this we pre-allocate buffers at the beginning of set operation, to prevent complete network loss Signed-off-by: Shradha Gupta <shradhagupta@linux.microsoft.com> Reviewed-by: Gerhard Engleder <gerhard@engleder-embedded.com> Reviewed-by: Haiyang Zhang <haiyangz@microsoft.com> Link: https://patch.msgid.link/1725248734-21760-1-git-send-email-shradhagupta@linux.microsoft.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2024-09-04eth: fbnic: Add support to fetch group statsMohsin Bashir
Add support for group stats for mac. The fbnic_set_counter help preserve the default values for counters which are not touched by the driver. The 'reset' flag in 'get_eth_mac_stats' allows to choose between resetting the counter to recent most value or fetching the aggregated values of the counter. The 'fbnic_stat_rd64' read 64b stats counters in an atomic fashion using read-read-read approach. This allows to isolate cases where counter is moving too fast making accuracy of the counter questionable.

2024-09-04net: sparx5: use contiguous memory for tx buffersDaniel Machon
Currently, the driver uses a linked list for storing the tx buffer addresses. This requires a good amount of extra bookkeeping code. Ditch the linked list in favor of tx buffers being in the same contiguous memory space as the DCB's and the DB's. The FDMA library has a helper for this - so use that. The tx buffer addresses are now retrieved as an offset into the FDMA memory space.

dev_err_probe()" This reverts commit bf4d87f884fe8a4b6b61fe4d0e05f293d08df61c because it introduced dev_err_probe() in non-probe path, which is not desired. In general, calling dev_err_probe() after successful probe in case of handling -EPROBE_DEFER error, will set deferred status on the device already probed. This is however not a problem here now, because dev_err_probe() in affected places is used for handling errors from request_firmware(), which does not return -EPROBE_DEFER. Still usage of dev_err_probe() in such case is not correct, because request_firmware() could once return -EPROBE_DEFER.

2024-09-03netdev_features: convert NETIF_F_FCOE_MTU to dev->fcoe_mtuAlexander Lobakin
Ability to handle maximum FCoE frames of 2158 bytes can never be changed and thus more of an attribute, not a toggleable feature. Move it from netdev_features_t to "cold" priv flags (bitfield bool) and free yet another feature bit.

2024-09-03netdev_features: convert NETIF_F_NETNS_LOCAL to dev->netns_localAlexander Lobakin
"Interface can't change network namespaces" is rather an attribute, not a feature, and it can't be changed via Ethtool. Make it a "cold" private flag instead of a netdev_feature and free one more bit. Signed-off-by: Alexander Lobakin <aleksander.lobakin@intel.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2024-09-03netdev_features: convert NETIF_F_LLTX to dev->lltxAlexander Lobakin
NETIF_F_LLTX can't be changed via Ethtool and is not a feature, rather an attribute, very similar to IFF_NO_QUEUE (and hot). Free one netdev_features_t bit and make it a "hot" private flag.

2024-09-03netdevice: convert private flags > BIT(31) to bitfieldsAlexander Lobakin
Make dev->priv_flags `u32` back and define bits higher than 31 as bitfield booleans as per Jakub's suggestion. This simplifies code which accesses these bits with no optimization loss (testb both before/after), allows to not extend &netdev_priv_flags each time, but also scales better as bits > 63 in the future would only add a new u64 to the structure with no complications, comparing to that extending ::priv_flags would require converting it to a bitmap. Note that I picked `unsigned long :1` to not lose any potential optimizations comparing to `bool :1` etc. Suggested-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Alexander Lobakin <aleksander.lobakin@intel.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
