* cxgb4: support running the driver on PCI functions besides 0Dimitris Michailidis2010-08-02
| | | | | | | | | Add support for running the driver on any PCI function. Mostly this entails replacing a constant 0 in a number of calls with the variable function number. Signed-off-by: Dimitris Michailidis <dm@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* cxgb4: get on-chip queue info from FW and create a memory window for themDimitris Michailidis2010-08-02
| | | | | | | | | | Get info about the availability of Tx on-chip queues from FW and if they are supported set up a memory window for them. iw_cxgb4 will be using them. Move the existing window setup later in the init sequence, after we have collected the new info. Signed-off-by: Dimitris Michailidis <dm@chelsio.com> Signed-off-by: David S.

* cxgb4: exclude registers with read side effects from register dumpsDimitris Michailidis2010-07-11
| | | | | | | | | | | A few registers have side effects on reads, eg FIFO pointers that auto advance or mailboxes which change ownership when read. They are unsafe to read so exclude them from ethtool register dumps. Bump ethtool_regs.version to indicate the changed register set.

* cxgb4: add user manipulation of the RSS tableDimitris Michailidis2010-07-11
| | | | | | | | | | Implement the get_rxnfc, get_rxfh_indir, and set_rxfh_indir ethtool methods for user manipulation of the RSS table. Besides the methods themselves the rest of the changes here store, initialize, and write the table contents. Signed-off-by: Dimitris Michailidis <dm@chelsio.com> Signed-off-by: David S.

* cxgb4: avoid duplicating some resource freeing codeDimitris Michailidis2010-07-11
| | | | | | | | Currently there are two copies of some resource freeing code, turn it into a function and call it. Signed-off-by: Dimitris Michailidis <dm@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* cxgb4: move the choice of interrupt type before net_device registrationDimitris Michailidis2010-07-11
| | | | | | | | | We need to settle on the kind of interrupts we'll be using, a choice that also impacts the number of queues, before registering and making visible the net_devices. Move the relevant code up a bit. Signed-off-by: Dimitris Michailidis <dm@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* cxgb4: fix for new ndo_get_stats64 signatureDimitris Michailidis2010-07-08
| | | | | | | | | The change to ndo_get_stats64 in "net: fix 64 bit counters on 32 bit arches" missed cxgb4. Fix it. Signed-off-by: Dimitris Michailidis <dm@chelsio.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* ethtool: Change ethtool_op_set_flags to validate flagsBen Hutchings2010-06-30
| | | | | | | | | | | | | | | | | | ethtool_op_set_flags() does not check for unsupported flags, and has no way of doing so. This means it is not suitable for use as a default implementation of ethtool_ops::set_flags. Add a 'supported' parameter specifying the flags that the driver and hardware support, validate the requested flags against this, and change all current callers to pass this parameter. Change some other trivial implementations of ethtool_ops::set_flags to call ethtool_op_set_flags().

* cxgb4: keep interrupts available when the ports are brought downDimitris Michailidis2010-05-18
| | | | | | | | | | The PF driver needs to remain alert while its ports are down to service requests or errors from virtual functions or FW so keep interrupts and queues available when the ports are brought down.
