Move the bcm_sf2 EEE-related functions to the b53 driver because this is shared code amongst Gigabit capable switch, only 5325 and 5365 are too old to support that.

Instead of repeating the same pattern: acquire mutex, read/write, release mutex, define a macro: b53_build_op() which takes the type (read|write), I/O size, and value (scalar or pointer). This helps with fixing bugs that could exist (e.g: missing barrier, lock etc.).

Vivien Didelot says: ==================== net: dsa: move master ethtool code The DSA core overrides the master device's ethtool_ops structure so that it can inject statistics and such of its dedicated switch CPU port. This ethtool code is currently called on unnecessary conditions or before the master interface and its switch CPU port get wired up. This patchset fixes this. Similarly to slave.c where the DSA slave net_device is the entry point of the dsa_slave_* functions, this patchset also isolates the master's ethtool code in a new master.c file, where the DSA master net_device is the entry point of the dsa_master_* functions. This is a first step towards better control of the master device and support for multiple CPU ports. ==================== Tested-by: NFlorian Fainelli <f.fainelli@gmail.com> Signed-off-by: NDavid S.

DSA overrides the master device ethtool ops, so that it can inject stats from its dedicated switch CPU port as well. The related code is currently split in dsa.c and slave.c, but it only scopes the master net device. Move it to a new master.c DSA core file. This file will be later extented with master net device specific code.

DSA overrides the master's ethtool ops so that we can inject its CPU port's statistics. Because of that, we need to setup the ethtool ops after the master's dsa_ptr pointer has been assigned, not before. This patch setups the ethtool ops after dsa_ptr is assigned, and restores them before it gets cleared.

There is no need to store a copy of the master ethtool ops, storing the original pointer in DSA and the new one in the master netdev itself is enough. In the meantime, set orig_ethtool_ops to NULL when restoring the master ethtool ops and check the presence of the master original ethtool ops as well as its needed functions before calling them.

skb->rbnode shares space with skb->next, skb->prev and skb->tstamp Current uses (TCP receive ofo queue and netem) need to save/restore tstamp, while skb->dev is either NULL (TCP) or a constant for a given queue (netem). Since we plan using an RB tree for TCP retransmit queue to speedup SACK processing with large BDP, this patch exchanges skb->dev and skb->tstamp.

Add three new traps needed for multicast routing: - PIM: Trap for PIM protocol control packets. - RPF: Trap for packets that fail the RPF check on a specific hardware route entry. - MULTICAST: Generic trap for multicast. It is used for routes that trap the packets to the CPU. The RPF and MULTICAST traps have rate limiters as these traps may have line-rate of packets trapped. The PIM trap has a rate limiter similarly to other L3 control protocols. The rate limiters are implemented by adding three new trap groups for the newly introduced traps.

The 'trivial' lpm implementation in this test allows equivalent nodes to be added (that is, nodes consisting of the same prefix and prefix length). For lookup operations, this is fine because insertion happens at the head of the (singly linked) list and the first, best match is returned. In order to support deletion, the tlpm data structue must first enforce uniqueness. This change modifies the insertion algorithm to search for equivalent nodes and remove them. Note: the BPF_MAP_TYPE_LPM_TRIE already has a uniqueness invariant that is implemented as node replacement.
