2016-09-01rtnetlink: fdb dump: optimize by saving last interface markersRoopa Prabhu
fdb dumps spanning multiple skb's currently restart from the first interface again for every skb. This results in unnecessary iterations on the already visited interfaces and their fdb entries. In large scale setups, we have seen this to slow down fdb dumps considerably. On a system with 30k macs we see fdb dumps spanning across more than 300 skbs. To fix the problem, this patch replaces the existing single fdb marker with three markers: netdev hash entries, netdevs and fdb index to continue where we left off instead of restarting from the first netdev. This is consistent with link dumps. In the process of fixing the performance issue, this patch also re-implements fix done by commit 472681d57a5d ("net: ndo_fdb_dump should report -EMSGSIZE to rtnl_fdb_dump") (with an internal fix from Wilson Kok) in the following ways: - change ndo_fdb_dump handlers to return error code instead of the last fdb index - use cb->args strictly for dump frag markers and not error codes. This is consistent with other dump functions. Below results were taken on a system with 1000 netdevs and 35085 fdb entries: before patch: $time bridge fdb show | wc -l 15065 real 1m11.791s user 0m0.070s sys 1m8.395s (existing code does not return all macs) after patch: $time bridge fdb show | wc -l 35085 real 0m2.017s user 0m0.113s sys 0m1.942s Signed-off-by: Roopa Prabhu <roopa@cumulusnetworks.com> Signed-off-by: Wilson Kok <wkok@cumulusnetworks.com> Signed-off-by: David S.

2016-08-22qed: Change locking scheme for VF channelYuval Mintz
Each VF employees a lock that's supposed to serialize its usage of the HW channel for communication with its PF, but the critical section is ill-defined: - VFs currently release the lock whenever the PF response arrives, prior to actually processing the reply buffer [which was also supposed to have been protected by same lock]. - The lock would be released on first response, ignoring the possibilty the sw flow isn't over [as might be the case of the acquisition flow]. As a result, the flow would run unprotected and would cause a double mutex release [as the additional message completion would release it while its actually already free]. Change the flow to have a dedicated function to be called at end of each flow and release the lock. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S.

2016-08-22qed*: Add support for VFs over legacy PFsYuval Mintz
Modern VFs can't run on old non-compatible as the fastpath HSI is slightly changed - but as the HSI is actually very close [basically, a single bit whose meaning flipped] this can be supported with small modifications. The major differences would be in: - Recognizing that VF is running on top of a legacy PF. - Returning some slowpath configurations that are no longer needed on top of modern PFs, but would be required when working over the legacy ones.

It also contains fixes for future qed* drivers that *hopefully* would be sent for review in the near future. In addition, it would allow driver some new functionality, including: - Allowing PF/VF driver compaitibility with old drivers [running pre-8.10.5.0 firmware]. - Better debug facilities.

2016-08-18qede: Fix Tx timeout due to xmit_moreYuval Mintz
Driver uses netif_tx_queue_stopped() to make sure the xmit_more indication will be honored, but that only checks for DRV_XOFF. At the same time, it's possible that during transmission the DQL will close the transmission queue with STACK_XOFF indication. In re-configuration flows, when the threshold is relatively low, it's possible that the device has no pending tranmissions, and during tranmission the driver would miss doorbelling the HW. Since there are no pending transmission, there will never be a Tx completion [and thus the DQL would not remove the STACK_XOFF indication], eventually causing the Tx queue to timeout. While we're at it - also doorbell in case driver has to close the transmission queue on its own [although this one is less important - if the ring is full, we're bound to receive completion eventually, which means the doorbell would only be postponed and not indefinetly blocked].
