2018-12-18net: hns3: getting tx and dv buffer size through firmwareYunsheng Lin
This patch adds support of getting tx and dv buffer size through firmware, because different version of hardware requires different size of tx and dv buffer. This patch also add dv_buf_size to tc' private buffer size even if pfc is not enable for the tc.

2018-12-18mlxsw: core: Increase timeout during firmware flash processShalom Toledo
During the firmware flash process, some of the EMADs get timed out, which causes the driver to send them again with a limit of 5 retries. There are some situations in which 5 retries is not enough and the EMAD access fails. If the failed EMAD was related to the flashing process, the driver fails the flashing. The reason for these timeouts during firmware flashing is cache misses in the CPU running the firmware. In case the CPU needs to fetch instructions from the flash when a firmware is flashed, it needs to wait for the flashing to complete. Since flashing takes time, it is possible for pending EMADs to timeout. Fix by increasing EMADs' timeout while flashing firmware.

2018-12-17nfp: flower: fix cb_ident duplicate in indirect block registerJohn Hurley
Previously the identifier used for indirect block callback registry and for block rule cb registry (when done via indirect blocks) was the pointer to the netdev we were interested in receiving updates on. This worked fine if a single app existed that registered one callback per netdev of interest. However, if multiple cards are in place and, in turn, multiple apps, then each app may register the same callback with the same identifier to both the netdev's indirect block cb list and to a block's cb list. This can lead to EEXIST errors and/or incorrect cb deletions. Prevent this conflict by using the app pointer as the identifier for netdev indirect block cb registry, allowing each app to register a unique callback per netdev. For block cb registry, the same app may register multiple cbs to the same block if using TC shared blocks. Instead of the app, use the pointer to the allocated cb_priv data as the identifier here. This means that there can be a unique block callback for each app/netdev combo.

2018-12-17bnxt_en: Disable MSIX before re-reserving NQs/CMPL rings.Michael Chan

This ensures that the MSIX vectors associated with the NQs/CMPL rings are still properly mapped when pci_disable_msix() masks the vectors. This patch will prevent errors when RDMA support is added for the new 57500 chips.

2018-12-17iwlwifi: mvm: don't send GEO_TX_POWER_LIMIT to old firmwaresEmmanuel Grumbach
Old firmware versions don't support this command. Sending it to any firmware before -41.ucode will crash the firmware. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=201975 Fixes: 66e839030fd6 ("iwlwifi: fix wrong WGDS_WIFI_DATA_SIZE") CC: <stable@vger.kernel.org> #4.19+ Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

Now that mlxsw driver handles all aspects of updating the Bloom filter mechanism, set bf_bypass value to false and allow HW to use Bloom filter. Signed-off-by: Nir Dotan <nird@mellanox.com> Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-12-16mlxsw: spectrum_acl: Set master RP index on transition to eRPNir Dotan
Bloom filter is updated on transitions from a single rule pattern, also called master RP, to eRP table and vice versa. Since rules are being written to or deleted from the Bloom filter on such transitions, it is not required to keep the same eRP bank ID for the master RP. Change master RP index assignment so it will be assigned with zero. This is consistent with the assignment of the first available spot that is used for allocating eRP's indices.

2018-12-16mlxsw: spectrum_acl: Update Bloom filter on eRP transitionsNir Dotan
Bloom filter update is required only for rules which reside on an eRP. When the region has only a single rule pattern then eRP table is not used, however insertion of another pattern would trigger a move to an active eRP table so it is imperative to update the Bloom filter with all previously configured rules. Add a method that updates Bloom filter entries for all rules currently configured in the region, on the event of a transition from master mask to eRP, or vice versa. For that purpose, maintain a list of all A-TCAM rules within mlxsw_sp_acl_atcam_region.

2018-12-16mlxsw: spectrum_acl: Set A-TCAM rules in Bloom filterNir Dotan
Add calls to eRP module for updating Bloom filter when a rule is added or removed from the A-TCAM. eRP module will update the Bloom filter only for cases in which the region has an active eRP table.
