2013-04-19net: vlan: prepare for 802.1ad VLAN filtering offloadPatrick McHardy1-2/+2
Change the rx_{add,kill}_vid callbacks to take a protocol argument in preparation of 802.1ad support. The protocol argument used so far is always htons(ETH_P_8021Q). Signed-off-by: Patrick McHardy <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2013-04-19net: vlan: rename NETIF_F_HW_VLAN_* feature flags to NETIF_F_HW_VLAN_CTAG_*Patrick McHardy1-4/+4
Rename the hardware VLAN acceleration features to include "CTAG" to indicate that they only support CTAGs. Follow up patches will introduce 802.1ad server provider tagging (STAGs) and require the distinction for hardware not supporting acclerating both.

2013-03-09drivers:net: Remove unnecessary OOM messages after netdev_alloc_skbJoe Perches1-7/+2
Emitting netdev_alloc_skb and netdev_alloc_skb_ip_align OOM messages is unnecessary as there is already a dump_stack after allocation failures. Other trivial changes around these removals: Convert a few comparisons of pointer to 0 to !pointer. Change flow to remove unnecessary label. Remove now unused variable. Hoist assignment from if.

2013-02-04ethernet: Remove unnecessary alloc/OOM messages, alloc cleanupsJoe Perches1-3/+1
alloc failures already get standardized OOM messages and a dump_stack. Convert kzalloc's with multiplies to kcalloc. Convert kmalloc's with multiplies to kmalloc_array. Fix a few whitespace defects. Convert a constant 6 to ETH_ALEN. Use parentheses around sizeof. Convert vmalloc/memset to vzalloc. Remove now unused size variables.

2012-12-07drivers/net: fix up function prototypes after __dev* removalsGreg Kroah-Hartman1-2/+2
The __dev* removal patches for the network drivers ended up messing up the function prototypes for a bunch of drivers. This patch fixes all of them back up to be properly aligned. Bonus is that this almost removes 100 lines of code, always a nice surprise. Signed-off-by: Greg Kroah-Hartman <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2012-05-10ehea: fix losing of NEQ events when one event occurred earlyThadeu Lima de Souza Cascardo1-0/+2
The NEQ interrupt is only triggered when there was no previous pending interrupt. If we request irq handling after an interrupt has occurred, we will never get an interrupt until we call H_RESET_EVENTS. Events seem to be cleared when we first register the NEQ. So, when we requested irq handling right after registering it, a possible race with an interrupt was much less likely. Now, there is a chance we may lose this race and never get any events. The fix here is to poll and acknowledge any events that might have happened right after registering the irq handler.

2012-04-26ehea: fix promiscuous modeThadeu Lima de Souza Cascardo1-5/+1
commit a4910b744486254cfa61995954c118fb2283c4fd has broken promiscuous mode, which is never set. port->promisc just reflects the last setting of PROMISCUOUS mode to avoid doing an extra hypercall when it's already set. However, since it may fail because of hypervisor permissions, we should still respect the multicast settings and not simply exit after setting promiscuous mode.

2012-04-26ehea: fix allmulticast supportThadeu Lima de Souza Cascardo1-9/+15
There was a bug in the mask of regtype parameter for registering a multicast filter. It was ignoring the scope bit, which was wrongly being used for all filters. The SCOPE_ALL value adds a filter that allows all multicast packets and ignores the MAC parameter, just what allmulticast needs. The normals filters, however, should not use SCOPE_ALL.

2012-04-24ehea: only register irq after setting up portsThadeu Lima de Souza Cascardo1-12/+18
If we receive an interrupt too early before we set up ports in the probe function, there won't be any port ready to handle it. Only registering the irq after the ports are setup fixes the problem, and works fine without losing any interrupts. This causes crashes in some situations: [c000000f7ff7fd60] d000000008e223f0 .ehea_neq_tasklet+0x78/0x148 [ehea] [c000000f7ff7fe00] c0000000000b6cac .tasklet_hi_action+0xdc/0x210 [c000000f7ff7fea0] c0000000000b7cc8 .__do_softirq+0x178/0x300 [c000000f7ff7ff90] c000000000022694 .call_do_softirq+0x14/0x24 [c000000f68ee7900] c000000000010e04 .do_softirq+0xec/0x110 [c000000f68ee79a0] c0000000000b789c .irq_exit+0xac/0xe0 [c000000f68ee7a20] c0000000000110bc .do_IRQ+0x114/0x2a8 [c000000f68ee7ae0] c00000000000553c hardware_interrupt_entry+0x18/0x1c Signed-off-by: David S.

commit 18604c548545 (ehea: NAPI multi queue TX/RX path for SMP) added driver specific logic for exiting napi mode.

2011-10-17ehea: Update multiqueue supportAnton Blanchard1-53/+39
The ehea driver had some multiqueue support but was missing the last few years of networking stack improvements: - Use skb_record_rx_queue to record which queue an skb came in on. - Remove the driver specific netif_queue lock and use the networking stack transmit lock instead. - Remove the driver specific transmit queue hashing and use skb_get_queue_mapping instead. - Use netif_tx_{start|stop|wake}_queue where appropriate. We can also remove pr->queue_stopped and just check the queue status directly. - Print all 16 queues in the ethtool stats. We now enable multiqueue by default since it is a clear win on all my testing so far. v3: [cascardo] fixed use_mcs parameter description [cascardo] set ehea_ethtool_stats_keys as const Signed-off-by: Anton Blanchard <[email protected]> Signed-off-by: Thadeu Lima de Souza Cascardo <[email protected]> Signed-off-by: David S.

Currently ehea ndo_get_stats can sleep in two places, in a hcall and in a GFP_KERNEL alloc, which is not correct.
