Although efx_init_port() is only called at probe time and so cannot race with port reconfiguration, most of the functions it calls can expect to be called with the MAC lock held. Signed-off-by:

Avoid overrunning the hardware limit of 4 concurrent RX queue flushes. Expand the queue flush state to support this. Make similar changes to TX flushing to keep the code symmetric. Signed-off-by:

Although all the defined fields in these registers are within 32 bits, they are architecturally defined as 128-bit like most other Falcon registers. In particular, we must use efx_reado() to ensure proper locking when reading MD_STAT_REG. Signed-off-by:

In order to support all three modes of macvlan at runtime, extend the existing netlink protocol to allow choosing the mode per macvlan slave interface. This depends on a matching patch to iproute2 in order to become accessible in user land. Signed-off-by:

This allows each macvlan slave device to be in one of three modes, depending on the use case: MACVLAN_PRIVATE: The device never communicates with any other device on the same upper_dev. This even includes frames coming back from a reflective relay, where supported by the adjacent bridge. MACVLAN_VEPA: The new Virtual Ethernet Port Aggregator (VEPA) mode, we assume that the adjacent bridge returns all frames where both source and destination are local to the macvlan port, i.e. the bridge is set up as a reflective relay. Broadcast frames coming in from the upper_dev get flooded to all macvlan interfaces in VEPA mode. We never deliver any frames locally. MACVLAN_BRIDGE: We provide the behavior of a simple bridge between different macvlan interfaces on the same port. Frames from one interface to another one get delivered directly and are not sent out externally. Broadcast frames get flooded to all other bridge ports and to the external interface, but when they come back from a reflective relay, we don't deliver them again. Since we know all the MAC addresses, the macvlan bridge mode does not require learning or STP like the bridge module does. Based on an earlier patch "macvlan: Reflect macvlan packets meant for other macvlan devices" by Eric Biederman. Signed-off-by:

We have very similar code for rx statistics in two places in the macvlan driver, with a third one being added in the next patch. Consolidate them into one function to improve overall readability of the driver. Signed-off-by:

The veth driver contains code to forward an skb from the start_xmit function of one network device into the receive path of another device. Moving that code into a common location lets us reuse the code for direct forwarding of data between macvlan ports, and possibly in other drivers. Signed-off-by:

The velocity hardware can handle up to 7 memory segments. This can be turned on and off via ethtool. The support was removed in commit 83c98a8c but is re-enabled and cleaned up here. It's off by default. Signed-off-by:

The VIA driver has changed the default for the DMA_LENGTH_DEF parameter. Together with adaptive interrupt supression and NAPI support, this improves performance quite a bit Signed-off-by:

This patch adds NAPI support for VIA velocity. The new velocity_poll function also pairs tx/rx handling twice which improves perforamance on some workloads (e.g., netperf UDP_STREAM) significantly (that part is from the VIA driver). Signed-off-by:

(Partially from the upstream VIA driver). Tweaking the number of frames-per-interrupt and timer-until-interrupt can reduce the amount of CPU work quite a lot. Signed-off-by:

(From the VIA driver). The current code does not guarantee 64-byte alignment since it simply does int add = skb->data & 63; skb->data += add; (via skb_reserve). So for example, if the skb->data address would be 0x10, this would result in 32-byte alignment (0x10 + 0x10). Correct by adding 64 - (skb->data & 63) instead. Signed-off-by:

Instead of using the hardcoded truncation for authentication algorithms, use the truncation length specified on xfrm_state. Signed-off-by:
-
Martin Willi authored
Adding a xfrm_state requires an authentication algorithm specified either as xfrm_algo or as xfrm_algo_auth with a specific truncation length. For compatibility, both attributes are dumped to userspace, and we also accept both attributes, but prefer the new syntax. If no truncation length is specified, or the authentication algorithm is specified using xfrm_algo, the truncation length from the algorithm description in the kernel is used. Signed-off-by:
-
Martin Willi authored
The new XFRMA_ALG_AUTH_TRUNC attribute taking a xfrm_algo_auth as argument allows the installation of authentication algorithms with a truncation length specified in userspace, i.e. SHA256 with 128 bit instead of 96 bit truncation. Signed-off-by:

Rewrite statistics accumulation to be in terms of structure fields, not raw u32 additions. Keep them in same order, though. This is the last user of create_proc_read_entry() in net/, please NAK all new ones as well as all new ->write_proc, ->read_proc and create_proc_entry() users. Cc me if there are problems. :-) Signed-off-by:

Ben Hutchings authored
efx_board::init_leds was introduced as a second stage of initialisation because of the inter-dependency between the board and PHY. We want to move board initialisation into NIC probing, which is too early to use MDIO, so SFN4111T initialisation also needs to be split. Signed-off-by:
