* bnxt_en: Fix ethtool -l pre-set max combined channel.Michael Chan2017-02-121-1/+1
| | | | | | | | | | | With commit d1e7925e6d80 ("bnxt_en: Centralize logic to reserve rings."), ring allocation for combined rings has become stricter. A combined ring must now have an rx-tx ring pair. The pre-set max. for combined rings should now be min(rx, tx). Fixes: d1e7925e6d80 ("bnxt_en: Centralize logic to reserve rings.")

* bnxt_en: Retry failed NVM_INSTALL_UPDATE with defragmentation flag.Kshitij Soni2017-02-121-6/+26
| | | | | | | | | | | | If the HWRM_NVM_INSTALL_UPDATE command fails with the error code NVM_INSTALL_UPDATE_CMD_ERR_CODE_FRAG_ERR, retry the command with a new flag to allow defragmentation. Since we are checking the response for error code, we also need to take the mutex until we finish reading the response.

* bnxt_en: Add a set of TX rings to support XDP.Michael Chan2017-02-071-4/+12
| | | | | | | | | | | Add logic for an extra set of TX rings for XDP. If enabled, this set of TX rings equals the number of RX rings and shares the same IRQ as the RX ring set. A new field bp->tx_nr_rings_xdp is added to keep track of these TX XDP rings. Adjust all other relevant functions to handle bp->tx_nr_rings_xdp.

* bnxt_en: Centralize logic to reserve rings.Michael Chan2017-02-071-30/+9
| | | | | | | | | | | | | | Currently, bnxt_setup_tc() and bnxt_set_channels() have similar and duplicated code to check and reserve rx and tx rings. Add a new function bnxt_reserve_rings() to centralize the logic. This will make it easier to add XDP_TX support which requires allocating a new set of TX rings. Also, the tx ring checking logic in bnxt_setup_msix() can be removed. The rings have been reserved before hand. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

* bnxt_en: Implement new scheme to reserve tx rings.Michael Chan2016-12-291-0/+15
| | | | | | | | | | | | In order to properly support TX rate limiting in SRIOV VF functions or NPAR functions, firmware needs better control over tx ring allocations. The new scheme requires the driver to reserve the number of tx rings and to query to see if the requested number of tx rings is reserved. The driver will use the new scheme when the firmware interface spec is 1.6.1 or newer. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* bnxt_en: Fix and clarify link_info->advertising.Michael Chan2016-12-291-2/+3
| | | | | | | | | | | The advertising field is closely related to the auto_link_speeds field. The former is the user setting while the latter is the firmware setting. Both should be u16. We should use the advertising field in bnxt_get_link_ksettings because the auto_link_speeds field may not be updated with the latest from the firmware yet.

* bnxt_en: Fix ethtool -l|-L inconsistent channel counts.Michael Chan2016-09-191-5/+7
| | | | | | | | | | | | | | | | | The existing code is inconsistent in reporting and accepting the combined channel count. bnxt_get_channels() reports maximum combined as the maximum rx count. bnxt_set_channels() accepts combined count that cannot be bigger than max rx or max tx. For example, if max rx = 2 and max tx = 1, we report max supported combined to be 2. But if the user tries to set combined to 2, it will fail because 2 is bigger than max tx which is 1. Fix the code to be consistent. Max allowed combined = max(max_rx, max_tx). We will accept a combined channel count <= max(max_rx, max_tx).

* | bnxt_en: Workaround Nitro A0 hardware RX bug (part 2).Prashant Sreedharan2016-07-191-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hardware is unable to drop rx packets not matching the RX filters. To workaround it, we create a special VNIC and configure the hardware to direct all packets not matching the filters to it. We then setup the driver to drop packets received on this VNIC. This patch creates the infrastructure for this VNIC, reserves a completion ring, and rx rings. Only shared completion ring mode is supported. The next 2 patches add a NAPI to handle packets from this VNIC and the setup of the VNIC.
