* net: core: dev: Add extack argument to dev_open()Petr Machata2018-12-061-1/+1
| | | | | | | | | | | | | | | | | In order to pass extack together with NETDEV_PRE_UP notifications, it's necessary to route the extack to __dev_open() from diverse (possibly indirect) callers. One prominent API through which the notification is invoked is dev_open(). Therefore extend dev_open() with and extra extack argument and update all users. Most of the calls end up just encoding NULL, but bond and team drivers have the extack readily available.

* enic: fix UDP rss bitsGovindarajulu Varadarajan2018-06-061-4/+14
| | | | | | | | | | | | | 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(). Signed-off-by: Govindarajulu Varadarajan <gvaradar@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* enic: allow adaptive coalesce setting for msi/legacy intrGovindarajulu Varadarajan2015-07-201-48/+65
| | | | | | | | | | | | | | | | | | | | * Allow setting of adaptive coalescing setting for all types of interrupt. * In msi & legacy intr, we use single interrupt for rx & tx. In this case tx_coalesce_usecs is invalid. We should use only rx_coalesce_usecs. Do not display tx_coal values for msi/intx. And do not allow user to set this as well. * Driver supports only tx/rx_coalesce_usec and adaptive coalesce settings. For other values, driver does not return error. So ethtool succeeds for unsupported values. Introduce enic_coalesce_valid() function to validate the coalescing values. * If user requests for coalesce value greater than what adaptor supports, driver uses the max value. We should at least log this. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* | net: Add full IPv6 addresses to flow_keysTom Herbert2015-06-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds full IPv6 addresses into flow_keys and uses them as input to the flow hash function. The implementation supports either IPv4 or IPv6 addresses in a union, and selector is used to determine how may words to input to jhash2. We also add flow_get_u32_dst and flow_get_u32_src functions which are used to get a u32 representation of the source and destination addresses. For IPv6, ipv6_addr_hash is called. These functions retain getting the legacy values of src and dst in flow_keys. With this patch, Ethertype and IP protocol are now included in the flow hash input.

| | | | | | | | | | | | | | | | | | | | | | | enic_set_coalesce() has two problems. * It should return -EINVAL and not -EOPNOTSUPP for invalid coalesce values. * In case of MSIX, enic_set_coalesce return error after applying requested coalescing setting partially. We should either apply all the setting requeste and return success or apply non and return error. * This patch also simplifies the algo. This was introduced by '7c2ce6e60f703 enic: Add support for adaptive interrupt coalescing' These changes were suggested by Ben Hutchings here http://www.spinics.net/lists/netdev/msg283972.html Also change enic driver version.

* enic: Add support for adaptive interrupt coalescingSujith Sankar2014-05-211-6/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for adaptive interrupt coalescing. For small pkts with low pkt rate, we can decrease the coalescing interrupt dynamically which decreases the latency. This however increases the cpu utilization. Based on testing with different coal intr and pkt rate we came up with a table(mod_table) with rx_rate and coalescing interrupt value where we get low latency without significant increase in cpu. mod_table table stores the coalescing timer percentage value for different throughputs. Function enic_calc_int_moderation() calculates the desired coalescing intr timer value. This function is called in driver rx napi_poll. The actual value is set by enic_set_int_moderation() which is called when napi_poll is complete. i.e when we unmask the rx intr. Adaptive coal intr is support only when driver is using msix intr. Because intr is not shared. Struct mod_range is used to store only the default adaptive coalescing intr value. Adaptive coal intr calue is calculated by timer = range_start + ((rx_coal->range_end - range_start) * mod_table[index].range_percent / 100); rx_coal->range_end is the rx-usecs-high value set using ethtool. range_start is rx-usecs-low, set using ethtool, if rx_small_pkt_bytes_cnt is greater than 2 * rx_large_pkt_bytes_cnt. i.e small pkts are dominant. Else its rx-usecs-low + 3.
