2018-06-06enic: fix UDP rss bitsGovindarajulu Varadarajan1-1/+1
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().

2018-03-04enic: set UDP rss flagGovindarajulu Varadarajan1-0/+1
New hardware needs UDP flag set to enable UDP L4 rss hash. Add ethtool get option to display supported rss flow hash. Signed-off-by: Govindarajulu Varadarajan <gvaradar@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-03-04enic: Add vxlan offload support for IPv6 pktsGovindarajulu Varadarajan1-1/+1
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>
2017-02-09enic: add devcmds for vxlan offloadGovindarajulu Varadarajan1-0/+5
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>
2015-10-05enic: do hang reset only in case of tx timeoutGovindarajulu Varadarajan1-0/+2
The current code invokes hang reset in case of error interrupt. We should hang reset only in case of tx timeout. This because of the way hang reset is implemented in firmware. Hang reset takes more firmware resources than soft reset. Adaptor does not generate error interrupt in case of tx timeout. Hang reset only in case of tx timeout, in .ndo_tx_timeout. Do soft reset otherwise. Introduce deferred work, enic_tx_hang_reset, to do hang reset. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-17enic: add devcmd2Govindarajulu Varadarajan1-0/+3
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.

2015-08-17enic: move struct definition from .c to .h fileGovindarajulu Varadarajan1-1/+39
Some of the structure definitions are in .c file to make them private to that file. This patch moves the struct definition to .h file, So that their definitions are accessible from other files.

2014-06-23enic: devcmd for adding IP 5 tuple hardware filtersGovindarajulu Varadarajan1-0/+2
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>
2014-06-02enic: Update driver to use __dev_uc/mc_sync/unsync callsAlexander Duyck1-2/+2
This change updates the enic driver to make use of __dev_uc_sync and __dev_mc_sync calls. Previously the driver was doing its own list management by storing the mc_addr and uc_addr list in a 32 address array. With this change the sync data is stored in the netdev_addr_list structures and instead we just track how many addresses we have written to the device. When we encounter 32 we stop and print a message as occurred previously with the old approach. Other than the core change the only other bit needed was to propagate the constant attribute with the MAC address as there were several spots where is twas only passed as a u8 * instead of a const u8 *. This patch is meant to maintain the original functionality without the use of the mc_addr and uc_addr arrays.
