The KSZ8081 PHY has a factory test mode which is set at the de-assertion of the reset line based on the RXER (KSZ8081RNA/RND) or TXC (KSZ8081MNX/RNB) pin. If a pull-down is missing, or if the pin has a pull-up, the factory test mode should be cleared by manually writing a 0 (according to the datasheet).

Daniel Borkmann says: ==================== pull-request: bpf-next 2019-04-28 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Introduce BPF socket local storage map so that BPF programs can store private data they associate with a socket (instead of e.g. separate hash table), from Martin. 2) Add support for bpftool to dump BTF types. This is done through a new `bpftool btf dump` sub-command, from Andrii. 3) Enable BPF-based flow dissector for skb-less eth_get_headlen() calls which was currently not supported since skb was used to lookup netns, from Stanislav. 4) Add an opt-in interface for tracepoints to expose a writable context for attached BPF programs, used here for NBD sockets, from Matt. 5) BPF xadd related arm64 JIT fixes and scalability improvements, from Daniel. 6) Change the skb->protocol for bpf_skb_adjust_room() helper in order to support tunnels such as sit. Add selftests as well, from Willem. 7) Various smaller misc fixes. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2019-04-27ibmvnic: Add device identification to requested IRQsMurilo Fossa Vicentini2-4/+11
The ibmvnic driver currently uses the same fixed name when using request_irq, this makes it hard to parse when multiple VNIC devices are available at the same time. This patch adds the unit_address as the device identification along with an id for each queue. The original idea was to use the interface name as an identifier, but it is not feasible given these requests happen at adapter probe, and at this point netdev is not yet registered so it doesn't have the proper name assigned to it.
