2017-08-28bnxt_en: fix clearing devlink ptr from bnxt structSathya Perla2-7/+11
The routine bnxt_link_bp_to_dl() is used to set the devlink ptr in bnxt struct (bp) and also to set the bnxt back ptr in the devlink struct. If devlink_register() fails, bp->dl must be cleared which is not happening currently. This patch fixes bnxt_link_bp_to_dl() to clear bp->dl by passing a NULL dl ptr.

2017-08-28bnxt_en: Improve -ENOMEM logic in NAPI poll loop.Michael Chan1-0/+7
If we cannot allocate RX buffers in the NAPI poll loop when processing an RX event, the current code does not count that event towards the NAPI budget. This can cause us to potentially loop forever in NAPI if we consistently cannot allocate new buffers. Improve it by counting -ENOMEM event as 1 towards the NAPI budget.

2017-08-28bnxt: initialize board_info values with proper enumsScott Branden1-32/+32
initialize board_info values with proper enums for defensive programming purposes. This will avoid any errors of the enums being declared not lining up with the board_info array.

2017-08-28bnxt_en: assign CPU affinity hints to bnxt_en IRQsVasundhara Volam2-2/+27
This patch provides hints to irqbalance to map bnxt_en device IRQs to specific CPU cores. cpumask_local_spread() is used, which first maps IRQs to near NUMA cores; when those cores are exhausted, IRQs are mapped to far NUMA cores.

2017-08-28bnxt_en: Improve tx ring reservation logic.Michael Chan4-14/+44
When the number of TX rings is changed (e.g. ethtool -L, enabling XDP TX rings, etc), the current code tries to reserve the new number of TX rings before closing and re-opening the NIC. If we are unable to reserve the new TX rings, we abort the operation and keep the current TX rings. The problem is that the firmware will disable the current TX rings even when it cannot reserve the new set of TX rings. We fix it as follows: 1. Instead of reserving the new set of TX rings, just ask the firmware to check if the new set of TX rings is available. There is a flag in the firmware message to do that. If not available, abort and the current TX rings will not be disabled. 2. Do the actual TX ring reservation in the path that opens the NIC. We keep the number of TX rings currently successfully reserved. If the number of TX rings is different than the reserved TX rings, we call firmware and reserve again.

2017-08-28ftgmac100: Support NCSI VLAN filtering when availableSamuel Mendoza-Jonas1-0/+5
Register the ndo_vlan_rx_{add,kill}_vid callbacks and set the NETIF_F_HW_VLAN_CTAG_FILTER if NCSI is available. This allows the VLAN core to notify the NCSI driver when changes occur so that the remote NCSI channel can be properly configured to filter on the set VLAN tags.

2017-08-28net/ncsi: Configure VLAN tag filterSamuel Mendoza-Jonas4-4/+326
Make use of the ndo_vlan_rx_{add,kill}_vid callbacks to have the NCSI stack process new VLAN tags and configure the channel VLAN filter appropriately. Several VLAN tags can be set and a "Set VLAN Filter" packet must be sent for each one, meaning the ncsi_dev_state_config_svf state must be repeated. An internal list of VLAN tags is maintained, and compared against the current channel's ncsi_channel_filter in order to keep track within the state. VLAN filters are removed in a similar manner, with the introduction of the ncsi_dev_state_config_clear_vids state. The maximum number of VLAN tag filters is determined by the "Get Capabilities" response from the channel. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com> Signed-off-by: David S.
