The patch fixes the case when adding a zero value to the packet pointer. The verifer reports the following error: [...] R0=imm0,min_value=0,max_value=0 R1=pkt(id=0,off=0,r=4) R2=pkt_end R3=fp-12 R4=imm4,min_value=4,max_value=4 R5=pkt(id=0,off=4,r=4) 269: (bf) r2 = r0

[PATCH net-next 0/8] ARM: Alpine: Ethernet support

Hello all, This series intend to add Ethernet support for the Annapurna Labs Alpine v1 (ARM) and v2 (ARM64). The series first adds helpers for the I/O fabric interrupt controller that is found in many controllers on the Alpine, then helpers for the so called "Universal DMA" (UDMA) are also added

[PATCH net-next 1/9] sunvnet: make sunvnet common code dynamically loadable

When the sunvnet_common code was split out for use by both sunvnet and the newer ldmvsw, it was made into a static kernel library, which limits the usefulness of sunvnet and ldmvsw as loadables, since most of the real work is being done in the shared code. Also, this is simply dead code in

[PATCH net-next 9/9] ldmvsw: disable tso and gso for bridge operations

The ldmvsw driver is specifically for supporting the ldom virtual networking by running in the primary ldom and using the LDC to connect the remaining ldoms to the outside world via a bridge. With TSO and GSO supported while connected the bridge, things tend to misbehave as seen in our case by

[PATCH net-next 7/9] sunvnet: remove extra rcu_read_unlocks

The RCU read lock is grabbed first thing in sunvnet_start_xmit_common() so it always needs to be released. This removes the conditional release in the dropped packet error path and removes a couple of superfluous calls in the middle of the code. Reported-by: Bijan Mottahedeh

[PATCH net-next 0/9] sunvnet driver updates

The sunvnet ldom virtual network driver was due for some updates and a bugfix or two. These patches address a few items left over from last year's make-over. Shannon Nelson (8): sunvnet: make sunvnet common code dynamically loadable sunvnet: update version and version printing sunvnet: add

From: Sowmini Varadhan The vio_dring_state *dr variable is unused in maybe_tx_wakeup(). As the comments indicate, we call maybe_tx_wakeup() whenever we get a STOPPED LDC message on the port. If the queue is stopped, we want to wake it up so that we will send another

[PATCH net-next 5/6] net: dsa: add switch notifier

Add a notifier block per DSA switch, registered against a notifier head in the switch fabric they belong to. This infrastructure will allow to propagate fabric-wide events such as port bridging, VLAN configuration, etc. If a DSA switch driver cares about cross-chip configuration, such events can

Simplify the code handling the slave netdevice notifier call by providing a dsa_slave_changeupper helper for NETDEV_CHANGEUPPER, and so on (only this event is supported at the moment.) Return NOTIFY_DONE when we did not care about an event, and NOTIFY_OK when we were concerned but no error
