* stmmac: fix parameter to dwmac4_set_umac_addr()Ben Dooks2016-06-101-1/+1
| | | | | | | | | | | | | | | | | | The dwmac4_set_umac_addr() takes a struct mac_device_info as the first parameter, but is being passed a ioaddr instead from dwmac4_set_filter(). Fix the warning/bug by changing the first parameter. drivers/net/ethernet/stmicro/stmmac/dwmac4_core.c:159:46: warning: incorrect type in argument 1 (different address spaces) drivers/net/ethernet/stmicro/stmmac/dwmac4_core.c:159:46: expected struct mac_device_info *hw drivers/net/ethernet/stmicro/stmmac/dwmac4_core.c:159:46: got void [noderef] <asn:2>*ioaddr Note, only compile tested this as do not have any hardware with it in.

* net/mlx5e: Fix blue flame quota logicEli Cohen2016-06-101-1/+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.

* net/mlx5: E-Switch, Modify node guid on vf set MACNoa Osherovich2016-06-102-2/+59
| | | | | | | | | | | | | | | | | In RoCE, the RDMA-CM needs the node guid to establish connection between nodes. Today, the node guid exposed to mlx5 Ethernet VFs is zero, therefore RDMA-CM on the VF is broken. Whenever the administrator sets a MAC for a VF, derive the node guid from it and set it as well in the following way: MAC: e4:1d:2d:b3:f4:01 -> node_guid: e4:1d:2d:ff:fe:b3:f4:01 Fixes: 77256579c6b43 ('net/mlx5: E-Switch, Introduce Vport...')

* net/mlx5: E-Switch, Use the correct error check on returned pointersOr Gerlitz2016-06-101-17/+17
| | | | | | | | | | | | | | | | | The mlx5 flow-steering API (mlx5_create_flow_table/group/rule) never returns null pointer on error. Even if it was doing that, checking for IS_ERR_OR_NULL(p) and then returning PTR_ERR(p) would have cause bugs, since PTR_ERR(NULL) --> success, crash. To make things more robust and protect against related future bugs, convert all IS_ERR_OR_NULL checks on returned values to IS_ERR.

| | | | | | | | | | | | | | | | | | | | | When a port is created following a split / unsplit we need to map it to the correct module and lane, enable it and then continue to initialize its various parameters such as MTU and VLAN filters. Under certain conditions, such as trying to split ports at the bottom row of the front panel by four, we get firmware errors. After evaluating this with the firmware team it was decided to alter the split / unsplit flow, so that first all the affected ports are mapped, then enabled and finally each is initialized separately. Fix the split / unsplit flow by first mapping and enabling all the affected ports. Newer firmware versions will support both flows.

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.

| | | | | | | | | | | | | | If an external Gigabit PHY is connected to either of the MACs we need to be able to tell the PHY to use a delay. Not doing so will result in heavy packet loss and/or data corruption when using PHYs such as the IC+ IP1001. We tell the PHY which MII delay mode to use via the devictree.

This rearranges the code so we bail out in either of the two cases and print a warning instead of accessing the uninitialized data. The qed_link_output structure remains untouched in this case, but all callers first call memset() on it, so at least we are not leaking stack data then.

| | | | | | | | | | | | | | | | | | Currently 100g devices don't support minimum/maximum BW configurations, yet link flaps might cause the driver to attempt to do such a configuration. Prevent this just as we do for the maximum BW. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | Commit 39651abd2814 ("qed: add support for dcbx") is re-configuring the QM hw-block as part of its sequence. This is done in attention handling context which is non-sleepable, yet memory is allocated in this flow using GFP_KERNEL.

| | | | | | | | | | | | | | | | | | | | PFs and VFs differ in their registered ethtool operations, but they're using a common function for get_sset_count(). As a result, `ethtool -i' for a VF would indicate it supports selftest, although that's not the case. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S.

| * qede: Reload on GRO changesYuval Mintz2016-05-261-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | Since driver is using a FW-based GRO implementation, this has some effects on its ability to cope with GRO enablement/disablement. As a result, driver must perform an inner-reload as a result of a state change in the offload configuration of said feature. [Failure to do so means network stack would continue to receive aggregated packets even though user requested the feature to be disabled].

| * net/mlx4_en: get rid of ret_statsEric Dumazet2016-05-262-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mlx4 uses a private struct net_device_stats in a vain attempt to avoid races. This is buggy because multiple cpus could call mlx4_en_get_stats() at the same time, so ret_stats can not guarantee stable results. To fix this, we need to switch to ndo_get_stats64() as this method provides per-thread storage. This allows to reduce mlx4_en_priv bloat.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) mlx4_en_xmit() can increment priv->stats.tx_dropped, but this variable is overwritten in mlx4_en_DUMP_ETH_STATS(). 2) This increment was not SMP safe, as a port might have many TX queues. Add a per TX ring tx_dropped to fix these issues. This is u32 as mlx4_en_DUMP_ETH_STATS() will add a 32bit field. So lets avoid bugs with SNMP agents having to cope with partial overwraps.
