* be2net: fix RX fragment posting for jumbo framesAjit Khaparde2014-09-131-7/+15
| | | | | | | | | | | | | | | In the RX path, the driver currently consumes upto 64 (budget) packets in one NAPI sweep. When the size of the packet received is larger than a fragment size (2K), more than one fragment is consumed for each packet. As the driver currently posts a max of 64 fragments, all the consumed fragments may not be replenished. This can cause avoidable drops in RX path. This patch fixes this by posting a max(consumed_frags, 64) frags. This is done only when there are atleast 64 free slots in the RXQ.

* be2net: fix some log messagesVasundhara Volam2014-09-131-9/+8
| | | | | | | | | | | | | This patch fixes the following minor issues with log messages in be2net: 1) Period is not required at the end of log message. 2) Remove "Unknown grp5 event" logs to reduce noise. The driver can safely ignore async events from FW it's not interested in. 3) Reword a log message for better readability to say that SRIOV "is disabled" rather than "not supported".

This also allows for supporting RSS queues on VFs, when less number of VFs are enabled per PF. When maximum number of VFs are enabled, each VF typically gets only one RXQ.

* be2net: fix qnq mode detection on VFsSuresh Reddy2014-06-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | The driver (on PF or VF) needs to detect if the function is in qnq mode for a HW hack in be_rx_compl_get() to work. The driver queries this information using the GET_PROFILE_CONFIG cmd (since the commit below can caused this regression.) But this cmd is not available on VFs and so the VFs fail to detect qnq mode. This causes vlan traffic to not work. The fix is to use the the adapter->function_mode value queried via QUERY_FIRMWARE_CONFIG cmd on both PFs and VFs to detect the qnq mode. Also QNQ_MODE was incorrectly named FLEX10_MODE; correcting that too as the fix reads much better with the name change.

| | | | | | | | | | | | | | | | | | | This patch improves MCCQ error status handling in the following ways: a) A MCC cmd completion returns a base-status and an addl-status. So far, the routine be_mcc_compl_process() returned only the "status" value. Now, embedd both statuses in the return value and let the caller routine access the value of interest using base_status() and addl_status() macros. b) Rename variables accordingly (base/addl) to avoid confusion while error checking. b) Some of the errors returned by FW are harmless and so an error msg is not logged for such errors.

The xfrm6_output.c has a bug fix which overlaps the renaming of skb->local_df to skb->ignore_df. In the Altera TSE driver cases, the register access cleanups in net-next overlapped with bug fixes done in net. Similarly a bug fix to send ALB packets in the bonding driver using the right source address overlaps with cleanups in net-next. Signed-off-by: David S. Miller <davem@davemloft.net>
| * be2net: enable interrupts in EEH resumeKalesh AP2014-05-141-0/+6
| | | | | | | | | | | | | | | | | | | | On some BE3 FW versions, after a HW reset, interrupts will remain disabled for each function. So, explicitly enable the interrupts in the eeh_resume handler, else after an eeh recovery interrupts wouldn't work.

* | net-next:v4: Add support to configure SR-IOV VF minimum and maximum Tx rate ↵Sucheta Chakraborty2014-05-231-8/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | through ip tool. o min_tx_rate puts lower limit on the VF bandwidth. VF is guaranteed to have a bandwidth of at least this value. max_tx_rate puts cap on the VF bandwidth. VF can have a bandwidth of up to this value. o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced which takes 4 arguments: netdev, VF number, min_tx_rate, max_tx_rate o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler. o Drivers that currently implement ndo_set_vf_tx_rate should now call ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet implemented by driver. o If user enters only one of either min_tx_rate or max_tx_rate, then, userland should read back the other value from driver and set both for IFLA_VF_RATE. Drivers that have not yet implemented IFLA_VF_RATE should always return min_tx_rate as 0 when read from ip tool. o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then IFLA_VF_RATE should override. o Idea is to have consistent display of rate values to user. o Usage example: - ./ip link set p4p1 vf 0 rate 900 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 900 (Mbps), max_tx_rate 900Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 300 min_tx_rate 200 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 300 (Mbps), max_tx_rate 300Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 600 rate 300 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5, tx rate 600 (Mbps), max_tx_rate 600Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a Signed-off-by: Sucheta Chakraborty <sucheta.chakraborty@qlogic.com> Signed-off-by: David S.

Mostly done via coccinelle script: @@ struct ethtool_ops *ops; struct net_device *dev; @@ - SET_ETHTOOL_OPS(dev, ops); + dev->ethtool_ops = ops; Compile tested only, but I'd seriously wonder if this broke anything.
