There are a couple of leftover symbol conflicts caused by hashtable.h being included by netdevice.h; those were not caught as build failure (they're "only" a warning, but in fact real bugs). Fix those up.

Sunil Goutham says: ==================== net: thunderx: Support for newer chips and miscellaneous patches This patch series adds support for VNIC on 81xx and 83xx SOCs. 81xx/83xx is different from 88xx in terms of capabilities and new type of interfaces supported (eg: QSGMII, RGMII) and have DLMs instead of QLMs which allows single BGX to have interfaces of different LMAC types. Also included some patches which are common for all 88xx/81xx/83xx SOCs like using netdev's name while registering irqs, reset receive queue stats and some changes to use standard API for split buffer Rx packets, generating RSS key e.t.c PS: Most of the patches were submitted earlier under different series but for some reason were not picked up by patchwork. Since new patches have been added in the meantime, resubmitting all as a new patchset. Changes from v1: - Incorporated Yuval Mintz's suggestion to use generic API to set minimum queue count i.e by using netif_get_num_default_rss_queues(). - Resolved a compilation issue reported by test robot while compiling patch 'Add support for 16 LMACs of 83xx' ==================== Signed-off-by: NDavid S.

Setting BGXX_SPUX_MISC_CONTROL::RX_PACKET_DIS is not needed as packet reception is anyway disabled by BGXX_CMRX_CONFIG::DATA_PKT_RX_EN. Also setting RX_PACKET_DIS causes a bogus remote fault condition which delays link detection. Signed-off-by: NSunil Goutham <sgoutham@cavium.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

When SQ/TXQ is reclaimed i.e reset it's stats also automatically reset by HW. This is not the case with RQ. Also VF doesn't have write access to statistics counter registers. Hence a new Mbox msg is introduced which supports resetting RQ, SQ and full Qset stats. Currently only RQ stats are being reset using this mbox message.

Instead of a round about way of converting buffers to SKBs and combining them into a frag list, use standard skb_add_rx_frag() API to merge page fragments.

This patch changes the way VF's irqs are visible in /proc/interrupts. Instead of VF id, logical interface's netdev name is used for IRQ naming and also all secondary VF's interrupts in multiqset config use primary VF's netdev name.

83xx has 4 BGX blocks and are enabled mixed QLM/DLM configs. BGX0/BGX1 are from QLM2/QLM3, BGX3 is DLM4 and BGX2 is split across DLM5 & DLM6.

This patch adds RGX/RGMII interface type support to BGX driver. This type of interface is supported by 81xx SOC.

On 88xx all LMACs in a BGX will be in same mode but on 81xx BGX can be split as two and there can be LMACs configured in different modes. These changes move lmac_type, lane2serdes fields into per lmac struct from BGX struct. Got rid of qlm_mode field which has become redundant with these changes. And now no of valid LMACs is read from CSRs configured by low level firmware and figuring out the same based on QLM mode is discarded Signed-off-by: NSunil Goutham <sgoutham@cavium.com> Signed-off-by: NDavid S.

Unlike 88xx, CQE_RX descriptor's tunnelling extension i.e CQE_RX2_S is always enabled on 81xx/83xx and HW does insert these fields into CQE_RX. As a result receive buffer addresses will now be present at 7th word of CQE_RX instead of 6th. Enable CQE_RX2_S on 88xx pass 2.x as well.

81xx has only 4 CPUs, so it doesn't make sense to initialize entire Qset i.e 8 queues by default. Made changes to queue initialization to init queues equal to number of CPUs or 8 queues whichever is lesser.
