* | | | net/mlx4_core: Work properly with EQ numbers > 256 in SRIOVYishai Hadas2015-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Firmware uses dynamic EQs allocation based on number of VFs and max EQs that can be allocated. As a result, VF can have EQ numbers that are larger than 256. According to the firmware spec, the max value is limited to be 1024 (10 bits), adapt the relevant code accordingly. This bug was impossible to hit prior to commit 7ae0e400cd93 ("net/mlx4_core: Flexible (asymmetric) allocation of EQs and MSI-X vectors for PF/VFs") which actually enables large number of EQs for VFs.

As a result, not all multicast traffic can be received on such device. Additionally, none of a vlan traffic can be received on such device as well. This patch propagates the promiscuous mode setting to lower device so that lower device may receive all packets that macvlan may be interested in.

At some point, when all RX buffers deplete, driver may fall into a sleep, and not recover when memory for new RX buffers is once again availible. This is because hardware does not have valid descriptors, so no interrupt will be generated for the driver to return to work in napi context. Fix it by schedule the napi poll function from stats_task delayed workqueue, as long as the allocations fail.

In non-debug mode, in current code, dump_rndis_message() will not dump anything but it still initialize some local variables and process the switch logic which is unnecessary, especially in high network throughput situation.

| * | bnx2x: really disable TPA if 'disable_tpa' option is setMichal Schmidt2015-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bnx2x's 'disable_tpa=1' module option is not respected properly and TPA (transparent packet aggregation) remains enabled. Even though the module option causes LRO to be disabled, TPA is enabled in GRO mode. Additionally, disabling GRO via ethtool then has no effect. One can still observe tpa_* statistics increase and large packets being received in tcpdump. The bug was an unintended consequence of commit aebf6244cd39 "bnx2x: Be more forgiving toward SW GRO". Fix it by following the bp->disable_tpa flag when initializing fp's. Signed-off-by: Michal Schmidt <mschmidt@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When PPP is used over a link which does not guarantee packet ordering, we might get late MPPE packets. This is a problem because MPPE must be kept synchronized and the current implementation does not drop them and rekey 4095 times instead of 0, which is wrong. In order to prevent rekeying about a whole count space times (~ 4095 times), drop packets which are not within the forward 4096/2 window and increase sanity error counter.
