* cxgb4/cxgb4vf: fix flow control display for auto negotiationRahul Lakkireddy2019-12-301-2/+2
| | | | | | | | | | | | | | | | | As per 802.3-2005, Section Two, Annex 28B, Table 28B-2 [1], when _only_ Rx pause is enabled, both symmetric and asymmetric pause towards local device must be enabled. Also, firmware returns the local device's flow control pause params as part of advertised capabilities and negotiated params as part of current link attributes. So, fix up ethtool's flow control pause params fetch logic to read from acaps, instead of linkattr.

* cxgb4: do not return DUPLEX_UNKNOWN when link is downGanesh Goudar2018-07-161-7/+4
| | | | | | | | | | | | | | | We were returning DUPLEX_UNKNOWN in get_link_ksettings() when the link was down. Unfortunately, this causes a problem when "ethtool -s autoneg on" is issued for a link which is down because the ethtool code first reads the settings and then reapplies them with only the changes provided on the command line. Which results in us diving into set_link_ksettings() with DUPLEX_UNKNOWN which is not DUPLEX_FULL, so set_link_ksettings() throws an -EINVAL error. do not return DUPLEX_UNKNOWN to fix the issue.

* treewide: use kv[mz]alloc* rather than opencoded variantsMichal Hocko2017-05-081-4/+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.
