2009-09-03enic: organize device initialization/deinit into separate functionsScott Feldman5-75/+133
To unclutter probe() a little bit, put all device initialization code in one spot and device deinit code in another spot. Also remove unused rq->buf_index variable/func. Signed-off-by: Scott Feldman <scofeldm@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-09-03enic: bug fix: check for zero port MTU before posting warningScott Feldman1-1/+1
Nic firmware can return zero for port MTU, so check for non-zero value before checking for change in port MTU. Signed-off-by: Scott Feldman <scofeldm@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-09-03enic: changes to driver/firmware interfaceScott Feldman4-10/+30

2009-09-03enic: provision for multiple Rx/Tx queues; prepare for RSS supportScott Feldman5-14/+50
Provision for multiple Rx/Tx queues. Max of 8 WQs and 8 RQs. Max for completion queue is 8+8=16 and max for interrupt resources is 8+8+2. Add driver/firmware interface for setting up RSS secret key and indirection table. Signed-off-by: Scott Feldman <scofeldm@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-09-03enic: bug fix: protect fw call i/f with spinlockScott Feldman1-0/+12
Some driver -> nic firmware calls weren't guarded with a spinlock, exposing the call i/f to a race between two threads Signed-off-by: Scott Feldman <scofeldm@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-09-03enic: use netdev_alloc_skbScott Feldman1-4/+6
Use netdev_alloc_skb rather than dev_alloc_skb Signed-off-by: Scott Feldman <scofeldm@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-09-03enic: bug fix: split TSO fragments larger than 16K into multiple descsScott Feldman1-18/+69
enic WQ desc supports a maximum 16K buf size, so split any send fragments larger than 16K into several descs. Signed-off-by: Scott Feldman <scofeldm@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-09-03enic: workaround A0 erratumScott Feldman4-4/+80
A0 revision ASIC has an erratum on the RQ desc cache on chip where the cache can become corrupted causing pkt buf writes to wrong locations. The s/w workaround is to post a dummy RQ desc in the ring every 32 descs, causing a flush of the cache. A0 parts are not production, but there are enough of these parts in the wild in test setups to warrant including workaround. A1 revision ASIC parts fix erratum.

2009-09-03enic: add support for multiple BARsScott Feldman4-36/+66
Nic firmware can place resources (queues, intrs, etc) on multiple BARs, so allow driver to discover/map resources beyond BAR0. Signed-off-by: Scott Feldman <scofeldm@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-09-02netdev: drivers should make ethtool_ops constStephen Hemminger1-1/+1
No need to put ethtool_ops in data, they should be const. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-09-01netdev: convert bulk of drivers to netdev_tx_tStephen Hemminger1-1/+2
In a couple of cases collapse some extra code like: int retval = NETDEV_TX_OK; ... return retval; into return NETDEV_TX_OK; Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-05-29net: dont update dev->trans_start in 10GB driversEric Dumazet1-2/+0
Followup of commits 9d21493b4beb8f918ba248032fefa393074a5e2b and 08baf561083bc27a953aa087dd8a664bb2b88e8e (net: tx scalability works : trans_start) (net: txq_trans_update() helper) Now that core network takes care of trans_start updates, dont do it in drivers themselves, if possible. Multi queue drivers can avoid one cache miss (on dev->trans_start) in their start_xmit() handler. Exceptions are NETIF_F_LLTX drivers (vxge & tehuti) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-02-09enic: bug fix: tx_timeout reset path fix-upsScott Feldman1-16/+23
tx_timeout reset path needs to re-init dev and re-apply nic cfg to enable vlan stripping. Signed-off-by: Scott Feldman <scofeldm@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-02-09enic: record all bad FCS errs as frame errorsScott Feldman2-7/+4
Report all bad FCS errs as frames errs. This includes frames with bad FCS on wire detected by MAC and frames which may be truncated due to ingress FIFO overruns. No longer print a driver msg on bad FCS err. Signed-off-by: Scott Feldman <scofeldm@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-02-09enic: bug fix: return notify intr creditsScott Feldman3-7/+26
Return notify intr credits after notify intr from firmware. This is especially important for legacy PCI intr mode, where not returning credits would cause PBA to remain asserted which would get us right back into the ISR. Signed-off-by: Scott Feldman <scofeldm@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-01-21net: Remove redundant NAPI functionsBen Hutchings1-6/+6
Following the removal of the unused struct net_device * parameter from the NAPI functions named *netif_rx_* in commit 908a7a1, they are exactly equivalent to the corresponding *napi_* functions and are therefore redundant.

2009-01-11netdev: add missing set_mac_address hookStephen Hemminger1-0/+1

2008-12-26drivers/net/enic: fix sparse warning: make symbol staticHannes Eder1-1/+1
Fix this sparse warning: drivers/net/enic/vnic_dev.c:288:5: warning: symbol 'vnic_dev_capable' was not declared. Should it be static? Signed-off-by: Hannes Eder <hannes@hanneseder.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-22net: Remove unused netdev arg from some NAPI interfaces.Neil Horman1-6/+6
When the napi api was changed to separate its 1:1 binding to the net_device struct, the netif_rx_[prep|schedule|complete] api failed to remove the now vestigual net_device structure parameter. This patch cleans up that api by properly removing it.. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-11-21enic: enable ethtool LRO supportScott Feldman2-20/+24
Enable ethtool support for get/set_flags so LRO can be turned on/off by fwding drivers such as the bridge driver. LRO is not compatible with fwding drivers. Signed-off-by: Scott Feldman <scofeldm@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-11-20netdev: add more functions to netdevice opsStephen Hemminger1-1/+1
This patch moves neigh_setup and hard_start_xmit into the network device ops structure. For bisection, fix all the previously converted drivers as well. Bonding driver took the biggest hit on this. Added a prefetch of the hard_start_xmit in the fast path to try and reduce any impact this would have. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Convert this driver to network device ops. Compile tested only. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-11-03drivers/net: Kill now superfluous ->last_rx stores.David S. Miller1-1/+0
The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Drivers need not do it any more. Some cases had to be skipped over because the drivers were making use of the ->last_rx value themselves. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-27net: convert more to %pMJohannes Berg2-13/+4
A number of places still use %02x:...:%02x because it's in debug statements or for no real reason. Make a few of them use %pM. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-09-24enic: bug fix: don't set netdev->name too earlyScott Feldman2-76/+47
Bug fix: don't set netdev->name early before netdev registration. Setting netdev->name early with dev_alloc_name() would occasionally cause netdev registration to fail returning error that device was already registered. Since we're using netdev->name to name MSI-X vectors, we now need to move the request_irq after netdev registartion, so move it to ->open.
