Add VSI HW stats for unicast, multicast, and broadcast for Rx and Tx. Stop printing the netdev multicast value because it doesn't include Tx and would be confusing.

2014-06-06i40e: increase reset wait timeShannon Nelson1-1/+1
The wait time was originally too optimistic and the resets were failing after EMPR. This increases the loop count to wait considerably longer. This won't delay the actual wait longer than really needed, just allows us to poll more times as needed.

B0 Si blocks AQ registers when in Blank Flash mode - write is dropped, read gives 0xDEADBEEF. Introduce a simple check for a correct value in one of the AQ registers to be sure that AQ was configured correctly.

On the DM9000B, dm9000_msleep() is called during the dm9000_timeout() routine. Since dm9000_timeout() holds the main spinlock through the entire routine, mdelay() needs to be used rather than msleep().

2014-06-05dm9000: clean up edge-triggered irq compatibilityAndrew Ruder1-10/+22
DM9000 uses level-triggered interrupts. Some systems (PXA270) only support edge-triggered interrupts on GPIOs. Some changes are necessary to ensure that interrupts are not triggered while the GPIO interrupt is masked or we will miss the interrupt forever. * Make some helper functions called dm9000_mask_interrupts() and dm9000_unmask_interrupts() for readability. * dm9000_init_dm9000(): ensure that this function always leaves interrupts masked regardless of the state when it entered the function. This is primarily to support the situation in dm9000_open where the logic used to go: dm9000_open() dm9000_init_dm9000() unmask interrupts request_irq() If an interrupt occurred between unmasking the interrupt and requesting the irq, it would be missed forever as the edge event would never be seen by the GPIO hardware in the PXA270. This allows us to change the logic to: dm9000_open() dm9000_init_dm9000() dm9000_mask_interrupts() request_irq() dm9000_unmask_interrupts() * dm9000_timeout(), dm9000_drv_resume(): Add the missing dm9000_unmask_interrupts() now required by the change above. * dm9000_shutdown(): Use mask helper function * dm9000_interrupt(): Use mask/unmask helper functions Signed-off-by: Andrew Ruder <andrew.ruder@elecsyscorp.com> Signed-off-by: David S.

2014-06-05dm9000: clean up reset codeAndrew Ruder1-11/+5
* Change a hard-coded 0x3 to NCR_RST | NCR_MAC_LBK in dm9000_reset * Every single place where dm9000_init_dm9000 was ran, a dm9000_reset was called immediately before-hand. Bring dm9000_reset into dm9000_init_dm9000. * The following commit updated the dm9000_probe reset routine to use NCR_RST | NCR_MAC_LBK: 6741f40 DM9000B: driver initialization upgrade and a later commit added a bug-fix to always reset the chip twice: 09ee9f8 dm9000: Implement full reset of DM9000 network device Unfortunately, since the changes in 6741f40 were made by replacing the dm9000_probe dm9000_reset with the adjusted iow(), the changes in 09ee9f8 were not incorporated into the dm9000_probe reset.

2014-06-05xen-netback: Fix handling of skbs requiring too many slotsZoltan Kiss1-11/+25
A recent commit (a02eb4 "xen-netback: worse-case estimate in xenvif_rx_action is underestimating") capped the slot estimation to MAX_SKB_FRAGS, but that triggers the next BUG_ON a few lines down, as the packet consumes more slots than estimated. This patch introduces full_coalesce on the skb callback buffer, which is used in start_new_rx_buffer() to decide whether netback needs coalescing more aggresively. By doing that, no packet should need more than (XEN_NETIF_MAX_TX_SIZE + 1) / PAGE_SIZE data slots (excluding the optional GSO slot, it doesn't carry data, therefore irrelevant in this case), as the provided buffers are fully utilized.

2014-06-05MPLS: Use mpls_features to activate software MPLS GSO segmentationSimon Horman1-1/+27
If an MPLS packet requires segmentation then use mpls_features to determine if the software implementation should be used. As no driver advertises MPLS GSO segmentation this will always be the case. I had not noticed that this was necessary before as software MPLS GSO segmentation was already being used in my test environment. I believe that the reason for that is the skbs in question always had fragments and the driver I used does not advertise NETIF_F_FRAGLIST (which seems to be the case for most drivers). Thus software segmentation was activated by skb_gso_ok(). This introduces the overhead of an extra call to skb_network_protocol() in the case where where CONFIG_NET_MPLS_GSO is set and skb->ip_summed == CHECKSUM_NONE.

Jesse fixes an issue reported by Dave Jones where a couple of FD checks ended up using bitwise OR where it should have been bitwise AND. Neerav removes unused defines and macros for receive LRO. Fix the driver from allowing the user to set a larger MTU size that the hardware was being configured to support. Refactors send version which moves code in two places into a small helper function. Kamil modifies register diagnostics since register ranges can vary among the different NVMs to avoid false test results. So now we try to identify the full range and use it for a register test and if we fail to define the proper register range, we will only test the first register from that group. Then removes the check for large buffer since this was added in the case this structure changed in the future, since the AQ definition is now mature enough that this check is no longer necessary. Mitch fixes i40evf driver to allocate descriptors in groups of 32 since the hardware requires it. Also fixes a crash when the ring size changed because it would change the count before deallocating resources, causing the driver to either free nonexistent buffers or leak leftover buffers. Fixed the driver to notify the VF for all types of resets so the VF can attempt a graceful reinit. Shannon refactors stats collection to create a unifying stats update routine to call the various stat collection routines. Removes rx_errors and rx_missed stats since they were removed from the chip design. Added missing VSI statistics that the hardware offers but are not apart of the standard netdev stats. v2: dropped patch "i40e: Allow disabling of DCB via debugfs" from Neerav based on feedback from David Miller. ==================== Signed-off-by: David S.

since commit 3afc2167f60a327a2c1e1e2600ef209a3c2b75b7 scan in not working anymore, due to mac80211 requires rx frequency status information. This patch makes the driver report this information. While NOT scanning this is straightforward. While scanning the firmware performs RF sweep and we cannot track the actual tuning frequency, so this is guessed by parsing beacons and probe responses.

2014-06-05i40evf: fix crash when changing ring sizesMitch Williams3-13/+15
i40evf_set_ringparam was broken in several ways. First, it only changed the size of the first ring, and second, changing the ring size would often result in a panic because it would change the count before deallocating resources, causing the driver to either free nonexistent buffers, or leak leftover buffers. Fix this by storing the descriptor count in the adapter structure, and updating the count for each ring each time we allocate them. This ensures that we always free the right size ring, and always end up with the requested count when the device is (re)opened.
