Add 'likely' hint to test of rx_checksum_enabled. Don't count IP fragments; the IP stack can do that. Do count non-matching multicast packets. Signed-off-by:

The "bug9141 workaround" of setting TX_FLUSH_MIN_LEN_EN should really be considered as a normal bit of configuration rather than a workaround. Signed-off-by:

The strap bits are only important on Falcon A and all production boards using it have fixed-speed 10G PHYs. Replace dummy MAC operations with default MAC operations. Signed-off-by:

Reading standard registers on the QT2025C before its firmware has booted may cause the boot process to fail. Therefore, follow the recommended reset sequence before reading its id registers. Either order works for the QT2022C2, so don't differentiate. Signed-off-by:

Falcon can generate events for LASI interrupts from the PHY, but in practice we have never implemented this in reference designs. Instead we have polled, inserted the appropriate events, and then handled the events later. This is a waste of time and code. Instead, make PHY poll functions update the link state synchronously and report whether it changed. We can still make use of the LASI registers as a shortcut on the SFT9001. Signed-off-by:

Currently the UP/DOWN state of VLANs is synchronized to the state of the underlying device, meaning all VLANs are set down once the underlying device is set down. This causes all routes to the VLAN devices to vanish. Add a flag to specify a "loose binding" mode, in which only the operstate is transfered, but the VLAN device state is independant. Signed-off-by:

From: Steve Hodgson <shodgson@solarflare.com> Currently we can set multicast hash immediately (in atomic context) but must delay setting MAC promiscuity. There is not that much point in deferring one but not the other, and setting the multicast hash on Siena will involve a firmware request. So process them both in efx_mac_work(). Also, set the broadcast bit in the multicast hash in efx_set_multicast_list(), since this is required for both Falcon and Siena. Signed-off-by:

From: Steve Hodgson <shodgson@solarflare.com> Only the XMAC on Falcon needs help from the driver to poll and reset the MAC-PHY link (XAUI); GMII is a simple parallel bus and on later NICs firmware takes care of the XAUI link. Also, an XMAC interrupt currently schedules a work item which simply clears a flag (efx_nic::mac_up) to be checked by the regular monitor (or the next link reconfiguration, if that is sooner). Rename the flag to xmac_poll_required, changing its sense. Remove the needless indirection and just set the flag immediately. Call falcon_xmac_poll() directly where required. Add a new generic operation mac_op::check_fault to check the link outside of regular monitoring, as required during self-tests. (Note that this leaves us with an unused work item, but we will immediately have another use for it.) Signed-off-by:

From: Steve Hodgson <shodgson@solarflare.com> Currently we initiate MAC stats DMA and busy-wait for completion when stats are requested. We can improve on this with a periodic timer to initiate and poll for stats, and opportunistically poll when stats are requested. Since efx_nic::stats_disable_count and efx_stats_{disable,enable}() are Falcon-specific, rename them and move them accordingly. Signed-off-by: -

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:

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:

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:
