2019-11-13net: atlantic: Signedness bug in aq_vec_isr_legacy()Dan Carpenter1-1/+1
irqreturn_t type is an enum and in this context it's unsigned, so "err" can't be irqreturn_t or it breaks the error handling. In fact the "err" variable is only used to store integers (never irqreturn_t) so it should be declared as int. I removed the initialization because it's not required. Using a bogus initializer turns off GCC's uninitialized variable warnings. Secondly, there is a GCC warning about unused assignments and we would like to enable that feature eventually so we have been trying to remove these unnecessary initializers.

2019-11-07net: atlantic: implement UDP GSO offloadIgor Russkikh4-32/+40
atlantic hardware does support UDP hardware segmentation offload. This allows user to specify one large contiguous buffer with data which then will be split automagically into multiple UDP packets of specified size. Bulk sending of large UDP streams lowers CPU usage and increases bandwidth. We did estimations both with udpgso_bench_tx test tool and with modified iperf3 measurement tool (4 streams, multithread, 200b packet size) over AQC<->AQC 10G link. Flow control is disabled to prevent RX side impact on measurements.

2019-09-27net: aquantia: Fix aq_vec_isr_legacy() return valueDan Carpenter1-9/+6
The irqreturn_t type is an enum or an unsigned int in GCC. That creates to problems because it can't detect if the self->aq_hw_ops->hw_irq_read() call fails and at the end the function always returns IRQ_HANDLED. drivers/net/ethernet/aquantia/atlantic/aq_vec.c:316 aq_vec_isr_legacy() warn: unsigned 'err' is never less than zero. drivers/net/ethernet/aquantia/atlantic/aq_vec.c:329 aq_vec_isr_legacy() warn: always true condition '(err >= 0) => (0-u32max >= 0)' Fixes: 970a2e9864b0 ("net: ethernet: aquantia: Vector operations") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Reviewed-by: Igor Russkikh <igor.russkikh@aquantia.com> Signed-off-by: David S.

2019-08-31net: aquantia: fix out of memory condition on rx sideDmitry Bogdanov1-1/+2
On embedded environments with hard memory limits it is a normal although rare case when skb can't be allocated on rx part under high traffic. In such OOM cases napi_complete_done() was not called. So the napi object became in an invalid state like it is "scheduled". Kernel do not re-schedules the poll of that napi object. Consequently, kernel can not remove that object the system hangs on `ifconfig down` waiting for a poll. We are fixing this by gracefully closing napi poll routine with correct invocation of napi_complete_done. This was reproduced with artificially failing the allocation of skb to simulate an "out of memory" error case and check that traffic does not get stuck.

2019-08-31net: aquantia: linkstate irq should be oneshotIgor Russkikh1-1/+1
Declaring threaded irq handler should also indicate the irq is oneshot. It is oneshot indeed, because HW implements irq automasking on trigger. Not declaring this causes some kernel configurations to fail on interface up, because request_threaded_irq returned an err code. The issue was originally hidden on normal x86_64 configuration with latest kernel, because depending on interrupt controller, irq driver added ONESHOT flag on its own. Issue was observed on older kernels (4.14) where no such logic exists.

2019-08-31net: aquantia: reapply vlan filters on upDmitry Bogdanov1-0/+4
In case of device reconfiguration the driver may reset the device invisible for other modules, vlan module in particular. So vlans will not be removed&created and vlan filters will not be configured in the device. The patch reapplies the vlan filters at device start.

The new route handling in ip_mc_finish_output() from 'net' overlapped with the new support for returning congestion notifications from BPF programs. In order to handle this I had to take the dev_loopback_xmit() calls out of the switch statement. The aquantia driver conflicts were simple overlapping changes. Signed-off-by: David S.
