Introduce new access register named Ports Check Mask Register (PCMR) to control all HW checks on port. With this register, the driver can enable/disable Hardware FCS validation. When RXALL is enabled/disabled using ndo_set_features, enable/disable fcs check at HW. User can change HW configuration using rx-all flag at ethtool. Signed-off-by:

In current mlx5e ndo_set_features implementation, setting some features can success while others can fail. Today, we return one error code which doesn't reflect the current features status of the netdev at the end of the ndo callback. Set netdev->features with features which were successfully set in order to keep the current status in case of failure. For this purpose, define new Macro to set/unset specific feature in netdev->features. This patch introduces a mechanism that uses feature handlers for each feature. Set features will call a generic handler, which will then call a specific handler in his turn and update netdev->features according to it's return value. Each specific handler is responsible to perform driver specific actions, and updating params if needed. Signed-off-by:

Expose link_down_events counter through ethtool -S. This counter is read from PPort statistics, then proccessed and stored as a special handling software counter. This counter is stored along software counters since it is the only PPort counter that it's size is not 64 bits. Signed-off-by:

Redesign ethtool statistics handling and reporting in the driver: 1. Move counters to a separate file (en_stats.h). 2. Remove unnecessary dependencies between stats and strings. 3. Use counter descriptors which hold a name and offset for each counter, and will be used to decide which counters will be exposed. For example when adding a new software counter to ethtool, instead of: 1. Add to stats struct. 2. Add to strings struct in the same order. 3. Change macro defining number of software counters. The only thing needed is to link the new counter to a counter descriptor. VPort counters are a set of hardware traffic counters created automatically for each virtual port opened. PPort counters are a set of counters describing per physical port performance statistics. These counters are gathered from hardware register and divided to groups according to different protocols.

Florian Westphal says: ==================== net: core: remove TX_LOCKED support Not that many users left, lets kill it. TX_LOCKED was meant to be used by LLTX drivers when spin_trylock() failed. Stack then re-queued if collisions happened on different cpus or free'd the skb to prevent deadlocks. Most of the driver removal patches fall into one of three categories: 1. remove the driver-private tx lock (and LLTX flag), or... 2. convert spin_trylock to plain spin_lock, or... 3. convert TX_LOCKED to free+TX_OK Patches are grouped by these categories, last patch is the actual removal. All driver changes were compile tested only with exception of atl1e. ==================== Signed-off-by: -

similar to atl1c: lock is only used in ndo_start_xmit, but we also advertised LLTX, so remove that as well and let core stack handle tx locking. Allows to remove the TX_LOCKED return value from the driver. Cc: Jay Cliburn <jcliburn@gmail.com> Cc: Chris Snook <chris.snook@gmail.com> Signed-off-by:

If macvlan_common_newlink fails in register_netdevice after macvlan_init then it decrements port->count twice, first in macvlan_uninit (from register_netdevice or rollback_registered) and then again in macvlan_common_newlink. A similar problem may exist in the ipvlan driver. This patch consolidates modifications to port->count into macvlan_init and macvlan_uninit (thanks to Eric Biederman for suggesting this approach). v3: remove macvtap specific bits. Signed-off-by:

The firmware can send a set of asynchronous replies through FW_PORT_CMD with DCBX information when that's negotiated with the Link Peer. The old code always assumed that a FW_PORT_CMD reply was always a Get Port Information message. This change conditionalizes the code to only handle the Get Port Information messages and throws a warning if we don't understand what we've been given. Also refactor t4_handle_fw_rpl() so that core functionality performed by t4_handle_get_port_info() for a specified port. Signed-off-by:

There could be race between t4_eth_xmit() and t4_free_sge_resources() while freeing tx descriptors, take txq lock in t4_free_sge_resources(). We need to stop the xmit frame path which runs in bottom half context while unloading the driver using _bh variant of the lock. This is to prevent the deadlock between xmit and driver unload.
