2016-06-15net/mlx4_en: initialize cmd.context_lock spinlock earlierEric Dumazet2-1/+1
Maciej Żenczykowski reported lockdep warning a spinlock was not registered before being held in mlx4_cmd_wake_completions() cmd.context_lock initialization is not at the right place. 1) mlx4_cmd_use_events() can be called multiple times. Calling spin_lock_init() on a live spinlock can lead to hangs. 2) mlx4_cmd_wake_completions() can be called while lock has not been initialized.

2016-06-14net: alx: Work around the DMA RX overflow issueFeng Tang2-51/+14
Commit 26c5f03 uses a new skb allocator to avoid the RFD overflow issue. But from debugging without datasheet, we found the error always happen when the DMA RX address is set to 0x....fc0, which is very likely to be a HW/silicon problem. So one idea is instead of adding a new allocator, why not just hitting the right target by avaiding the error-prone DMA address? This patch will actually * Remove the commit 26c5f03 * Apply rx skb with 64 bytes longer space, and if the allocated skb has a 0x...fc0 address, it will use skb_resever(skb, 64) to advance the address, so that the RX overflow can be avoided. In theory this method should also apply to atl1c driver, which I can't find anyone who can help to test on real devices.

Configuring the PHY LED registers for the Marvell 88E1510 and others is not possible, because regardless of the values in marvell,reg-init, it is later overridden in m88e1121_config_aneg with a non-standard default.

2016-06-10net: mediatek: remove superfluous queue wake up callJohn Crispin1-5/+2
The code checks if the queue should be stopped because we are below the threshold of free descriptors only to check if it should be started again. If we do end up in a state where we are at the threshold limit, it makes more sense to just stop the queue and wait for the next IRQ to trigger the TX housekeeping again. There is no rush in enqueuing the next packet, it needs to wait for all the others in the queue to be dispatched first anyway. Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: David S.

But additionally the soft reset itself got conditional and is therefore also only performed if the phy is in power down state. This patch keeps the conditional wake up from power down, but re-introduces the unconditional soft reset using the generic soft reset function. It was tested on linux-4.1.25 and linux-4.7.0-rc2.

2016-06-09net/mlx5e: Fix blue flame quota logicEli Cohen1-1/+2
Blue flame is a latency enhancement feature that allows the driver to write the packet data directly to the NIC's registers thus making the read of the packet data from host memory redundant. We maintain a quota for the blue flame which is reloaded whenever we identify that the hardware is processing send requests and processes them fast enough so by the time we post the next send request it was able to process all the pending ones. This indicates that the hardware is capable of processing more blue flame requests efficiently. The blue flame quota is decremented whenever we send using blue flame. The current code erroneously clears the budget if we did not use blue flame for the current post send operation and we fix it here.

Since both CTAG and STAG rx acceleration must be enabled together, we only need to check one feature flag (NETIF_F_HW_VLAN_CTAG_RX) before calling __vlan_hwaccel_put_tag(). Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-07bnxt_en: Enable and disable RX CTAG and RX STAG VLAN acceleration together.Michael Chan1-0/+14
The hardware can only be set to strip or not strip both the VLAN CTAG and STAG. It cannot strip one and not strip the other. Add logic to bnxt_fix_features() to toggle both feature flags when the user is toggling one of them. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

2016-06-07bnxt_en: Fix tx push race condition.Michael Chan1-1/+2
Set the is_push flag in the software BD before the tx data is pushed to the chip. It is possible to get the tx interrupt as soon as the tx data is pushed. The tx handler will not handle the event properly if the is_push flag is not set and it will crash. Signed-off-by: Michael Chan <michael.chan@broadocm.com> Signed-off-by: David S.

2016-06-05bnx2x: allow adding VLANs while interface is downMichal Schmidt1-89/+62
Since implementing VLAN filtering in commit 05cc5a39ddb74 ("bnx2x: add vlan filtering offload") bnx2x refuses to add a VLAN while the interface is down: # ip link add link enp3s0f0 enp3s0f0_10 type vlan id 10 RTNETLINK answers: Bad address and in dmesg (with bnx2x.debug=0x20): bnx2x: [bnx2x_vlan_rx_add_vid:12941(enp3s0f0)]Ignoring VLAN configuration the interface is down Other drivers have no problem with this. Fix this peculiar behavior in the following way: - Accept requests to add/kill VID regardless of the device state. Maintain the requested list of VIDs in the bp->vlan_reg list. - If the device is up, try to configure the VID list into the hardware. If we run out of VLAN credits or encounter a failure configuring an entry, fall back to accepting all VLANs. If we successfully configure all entries from the list, turn the fallback off. - Use the same code for reconfiguring VLANs during NIC load.
