2017-05-21cxgb4 : retrieve port information from firmwareGanesh Goudar1-3/+31
issue get port information command to firmware to retrieve port information and update if it is different from what was last recorded and also add indication for supported link modes for firmware port types FW_PORT_TYPE_SFP28, FW_PORT_TYPE_KR_SFP28, FW_PORT_TYPE_CR4_QSFP.

2017-05-08treewide: use kv[mz]alloc* rather than opencoded variantsMichal Hocko1-4/+4
There are many code paths opencoding kvmalloc. Let's use the helper instead. The main difference to kvmalloc is that those users are usually not considering all the aspects of the memory allocator. E.g. allocation requests <= 32kB (with 4kB pages) are basically never failing and invoke OOM killer to satisfy the allocation. This sounds too disruptive for something that has a reasonable fallback - the vmalloc. On the other hand those requests might fallback to vmalloc even when the memory allocator would succeed after several more reclaim/compaction attempts previously. There is no guarantee something like that happens though. This patch converts many of those places to kv[mz]alloc* helpers because they are more conservative.

2015-10-22cxgb4: Restore L1 cfg, if FW rejects new L1 cfg settingsHariprasad Shenai1-4/+11

2015-09-28cxgb4: Add HW timesptamp support for RXHariprasad Shenai1-0/+15
Adds support for ethtool get time stamp ioctl, which is used by tcpdump to get the supported time stamp types eg: tcpdump -i eth5 -J Time stamp types for eth5 (use option -j to set): host (Host) adapter_unsynced (Adapter, not synced with system time) Adds support for adapter unsynced mode, by adding SIOCSHWTSTAMP support in driver.

2015-07-26cxgb4: Allow firmware flash, only if cxgb4 is the master driverHariprasad Shenai1-0/+14
Adapter can go for a toss, if cxgb4 is loaded as slave and we try to upgrade the firmware. So add a check for the same before flashing firmware using ethtool. Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-06-05cxgb4: Rename t4_link_start() to t4_link_l1cfgHariprasad Shenai1-2/+2
t4_link_start() was completely misnamed. It does _not_ start up the link. It merely does the L1 Configuration for the link. The Link Up process is started automatically by the firmware when the number of enabled Virtual Interfaces on a port goes from 0 to 1. So renaming this routine to t4_link_l1cfg() for better documentation. Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-05-27cxgb4/cxgb4vf: function and argument name cleanupHariprasad Shenai1-8/+8
This patch changes variable name 'fn' to 'pf' of structure adapter. A 'fn' usually stands for PCI function which could be a PF or a VF. However, the use of this particular variable is explicitly limited to PF only. So, be specific about it in the variable name. Also corrects arguments passed for fn t4_ofld_eq_free, t4_ctrl_eq_free, t4_eth_eq_free, t4_iq_free, t4_alloc_vi, t4_fw_hello, t4_wr_mbox and t4_cfg_pfvf function. Also renames cxgb4_t4_bar2_sge_qregs to t4_bar2_sge_qregs and renames the latter function name in cxgb4vf driver to t4vf_bar2_sge_qregs to avoid conflicts. Also fixes alignment for these function.
