2017-05-24qed: Enable RoCE parser searching on fp initMichal Kalderon1-0/+7

2017-05-24qed: Flush slowpath tasklet on stopTomer Tayar1-0/+14
Today, driver has a synchronization point while closing the device which synchronizes its slowpath interrupt line. However, that's insufficient as that ISR would schedule the slowpath-tasklet - so even after ISR is over it's possible the handling of the interrupt has not completed. By doing a disable/enable on the taskelt we guarantee that all HW events that should no longer be genereated from that point onward in the flow are truly behind us.

2017-05-21qed: Fix setting of Management bitfieldsTomer Tayar1-1/+1
The management firmware HSI contains masks which are already shifted to their right place, so QED_MFW_SET_FIELD() is clearing incorrect fields by shifting the mask by the offset. Luckily, today we set the fields in an incrementing order [so we're not erasing any previously set fields], but this still needs fixing.

Re-organize the logic that allocates and frees memory of various sub-components of the hw-function - a.

2017-05-21qede: Don't use an internal MAC fieldMintz, Yuval3-28/+38
Driver maintains its primary MAC in a private field which gets updated when ndo_dev_set_mac() gets called. However, there are flows where the primary MAC of the device can change without said NDO being called [bond device in TLB mode configuring slaves' addresses], resulting in a configuration where there's a mismatch between what's apparent to user [the netdevice's value] and what's configured in the HW [the private value]. As we don't have any real motivation of maintaining this private field, simply remove it and start using the netdevice's field instead.

2017-05-21qede: Allow WoL to activate by defaultMintz, Yuval1-0/+6
When management firmware declares that the device is WoL-capable, the default driver behavior would be to allow the management firmware to take the decision of whether it's actually needed or not. Problem is ethtool interface doesn't have a 'default' kind of option, and user would see the interface WoL as disabled, which doesn't accurately reflect the actual configuration. More-so, if the user actually wants to explicitly disable WoL he'd have to first enable it [otherwise ethtool would block the command]. Instead of allowing management to make the decision, enable WoL by default on all devices capable of it. Signed-off-by: Yuval Mintz <[email protected]> Signed-off-by: David S.

This pushes qed [and as result, all qed* drivers] into using 8.20.0.0 firmware. The changes are mostly contained in qed with minor changes to qedi due to some HSI changes. Content-wise, the firmware contains fixes to various issues exposed since the release of the previous firmware, including: - Corrects iSCSI fast retransmit when data digest is enabled. - Stop draining packets when receiving several consecutive PFCs. - Prevent possible assertion when consecutively opening/closing many connections. - Prevent possible assertion due to too long BDQ fetch time.

PTP hardware filter configuration performed by the driver for a given user requested config is not correct for some of the PTP modes.

Set the associated bits based on the user request. 2. ptp4l application fails to operate in Peer Delay mode. Following changes are needed to fix this, a.
