2015-11-16be2net: remove unused local rsstable arrayIvan Vecera
Remove rsstable array and its initialization from be_set_rss_hash_opts(). The array became unused after "e255787 be2net: Support for configurable RSS hash key". The initial RSS table is now filled and stored for later usage during Rx queue creation.

2015-10-16drivers/net: get rid of unnecessary initializations in .get_drvinfo()Ivan Vecera
Many drivers initialize uselessly n_priv_flags, n_stats, testinfo_len, eedump_len & regdump_len fields in their .get_drvinfo() ethtool op. It's not necessary as these fields is filled in ethtool_get_drvinfo(). v2: removed unused variable v3: removed another unused variable Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S.

2015-07-10be2net: make SET_LOOPBACK_MODE cmd asynchrounousSuresh Reddy
The SET_LOOPBACK_MODE command is always issued from ethtool only in a process context. So, while waiting for the cmd to complete, the driver can sleep instead of holding spin_lock_bh() on the mcc_lock. This is done by calling be_mcc_notify() instead of be_mcc_notify_wait() (that returns only after the cmd completes while the MCCQ is locked).

2015-06-07be2net: Replace dma/pci_alloc_coherent() calls with dma_zalloc_coherent()Sriharsha Basavapatna
There are several places in the driver (all in control paths) where coherent dma memory is being allocated using either dma_alloc_coherent() or the deprecated pci_alloc_consistent(). All these calls should be changed to use dma_zalloc_coherent() to avoid uninitialized fields in data structures backed by this memory.

2015-05-09be2net: set interrupt moderation for Skyhawk-R using EQ-DBPadmanabh Ratnakar
Currently adaptive interrupt moderation is set by calculating and configuring an EQ-delay every second. This is done via a FW-cmd. But, on Skyhawk-R a "re-arm to interrupt" delay can be set while ringing the EQ-DB. This patch uses this facility to calculate and set the interrupt delay every 1ms. This helps moderating interrupts better when the traffic is bursty.

2015-03-04be2net: avoid creating the non-RSS default RXQ if FW allows toVasundhara Volam
On BE2, BE3 and Skhawk-R chips one non-RSS (called "default") RXQ was needed to receive non-IP traffic. Some FW versions now export a capability called IFACE_FLAGS_DEFQ_RSS where this requirement doesn't hold. On such FWs the driver now does not create the non-RSS default queue. This prevents wasting one RXQ per VF. Signed-off-by: Vasundhara Volam <vasundhara.volam@emulex.com> Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

2015-01-05be2net: support TX batching using skb->xmit_more flagSathya Perla
This patch uses skb->xmit_more flag to batch TX requests. TX is flushed either when xmit_more is false or there is no more space in the TXQ. Skyhawk-R and BEx chips require an even number of wrbs to be posted. So, when a batch of TX requests is accumulated, the last header wrb may need to be fixed with an extra dummy wrb. This patch refactors be_xmit() routine as a sequence of be_xmit_enqueue() and be_xmit_flush() calls. The Tx completion code is also updated to be able to unmap/free a batch of skbs rather than a single skb. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

2014-12-08ethtool: Support for configurable RSS hash functionEyal Perry
This patch extends the set/get_rxfh ethtool-options for getting or setting the RSS hash function. It modifies drivers implementation of set/get_rxfh accordingly. This change also delegates the responsibility of checking whether a modification to a certain RX flow hash parameter is supported to the driver implementation of set_rxfh. User-kernel API is done through the new hfunc bitmask field in the ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an index in the new string-set ETH_SS_RSS_HASH_FUNCS. Got approval from most of the relevant driver maintainers that their driver is using Toeplitz, and for the few that didn't answered, also assumed it is Toeplitz.
