2018-06-06enic: fix UDP rss bitsGovindarajulu Varadarajan1-1/+19
In commit 48398b6e7065 ("enic: set UDP rss flag") driver needed to set a single bit to enable UDP rss. This is changed to two bit. One for UDP IPv4 and other bit for UDP IPv6. The hardware which supports this is not released yet. When released, driver should set 2 bit to enable UDP rss for both IPv4 and IPv6. Also add spinlock around vnic_dev_capable_rss_hash_type().

2018-03-05enic: set IG desc cache flag in openGovindarajulu Varadarajan1-0/+1
New adapter needs CMD_OPENF_IG_DESCCACHE flag to be set. If this flag is not set, fw flushes the global IG desc cache. This flag is nop in older adapter. Also increment driver version Signed-off-by: Govindarajulu Varadarajan <gvaradar@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-03-05enic: Check if hw supports multi wq with vxlan offloadGovindarajulu Varadarajan1-0/+1
Some adaptors do not support vxlan offload when multi wq is configured. If hw supports multi wq, BIT(2) is set in a1. Signed-off-by: Govindarajulu Varadarajan <gvaradar@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-03-05enic: Add vxlan offload support for IPv6 pktsGovindarajulu Varadarajan1-0/+3
New adaptors supports vxlan offload for inner IPv6 and outer IPv6 vxlan pkts. Fw sets BIT(0) & BIT(1) in a1 if hw supports ipv6 inner & outer pkt offload. Signed-off-by: Govindarajulu Varadarajan <gvaradar@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-02-10enic: add devcmds for vxlan offloadGovindarajulu Varadarajan1-0/+51
This patch adds devcmds needed for vxlan offload. Implement 3 new devcmd overlay_offload_ctrl: enable/disable offload overlay_offload_cfg: update offload udp port number get_supported_feature_ver: get hw supported offload version. Each version has different bitmap for csum_ok/encap Signed-off-by: Govindarajulu Varadarajan <gvaradar@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-18enic: add devcmd2Govindarajulu Varadarajan1-0/+5
devcmd is an interface for driver to communicate with fw/adaptor. It involves writing data to hardware registers and waiting for the result. This mechanism does not scale well. The queuing of "no wait" devcmds is done in firmware memory rather than on the host. Firmware memory is a rather more scarce and valuable resource than host memory. A devcmd storm from one vf can disrupt the service on other pf/vf. The lack of flow control allows for possible denial of server from one VM to another. Devcmd2 uses work queue to post the devcmds, just like tx work queue. This allows better flow control. Initialize devcmd2, if fails we fall back to devcmd1. Also change the driver version.

2014-06-24enic: devcmd for adding IP 5 tuple hardware filtersGovindarajulu Varadarajan1-0/+5
This patch adds interface to add and delete IP 5 tuple filter. This interface is used by Accelerated RFS code to steer a flow to corresponding receive queue. As of now adaptor supports only ipv4 + tcp/udp packet steering. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S. Miller <davem@davemloft.net>
