2017-02-19RDMA/bnxt_re: add DCB dependencyArnd Bergmann
When CONFIG_DCB is disabled, we get a link error: drivers/infiniband/built-in.o: In function `bnxt_re_setup_qos': trace.c:(.text+0x155774): undefined reference to `dcb_ieee_getapp_mask' trace.c:(.text+0x155774): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dcb_ieee_getapp_mask' trace.c:(.text+0x155794): undefined reference to `dcb_ieee_getapp_mask' trace.c:(.text+0x155794): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dcb_ieee_getapp_mask' Like the other drivers that use this function, a Kconfig dependency is the correct fix.

2017-02-19IB/hfi1: use size_t for passing array lengthArnd Bergmann
gcc-7 produces a mysterious warning about the size argument being potentially out of range: drivers/infiniband/hw/hfi1/verbs.c: In function 'init_cntr_names': drivers/infiniband/hw/hfi1/verbs.c:1644:2: error: 'memcpy': specified size between 18446744071562067968 and 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Werror=stringop-overflow=] This seems to refer to a the case where an 64-bit size_t gets truncated into a negative 'int' and subsequently turned into a high 64-bit number again.

2017-02-19IB/hfi1: Process qp wait list in IRQ thread periodicallyMike Marciniszyn
In the event that the IRQ thread is extremely busy, the processing of an rcd wait list can be delayed by quite a bit until the IRQ thread completes its work. The QP reset reference count wait can then appear to be stuck, thus causing up a QP destroy to emit the hung task diagnostic. Fix by processing the qp wait list periodically from the thread. The interval is a multiple (currently 4) of the MAX_PKT_RECV. Also, reduce some of the excessive inlining. The guidelines are per packet is ok inline, otherwise the choice is based on likelyhood of execution.

Fix, or rather, avoid a sparse warning caused by the fact that csum_replace_by_diff expects to receive a __wsum value. Since the calculation appears to work, simply typecast the passed paylen value to __wsum to avoid the warning. This seems pretty fishy since __wsum was obviously annotated as a separate type on purpose, so this throws the entire calculation into question. Since it currently appears to behave as expected, the typecast is probably safe.

2017-02-18i40e: Fix Adaptive ITR enablingCarolyn Wyborny
This patch fixes a bug introduced with the addition of the per queue ITR feature support in ethtool. With that addition, there were functions added which converted the ITR settings to binary values. The IS_ENABLED macros that run on those values check whether a bit is set or not and with the value being binary, the bit check always returned ITR disabled which prevents any updating of the ITR rate. This patch fixes the problem by changing the functions to return the current ITR value instead and renaming it to better reflect its function. These functions now provide a value which will be accurately asessed and update the ITR as intended.

2017-02-18i40e: remove unnecessary call to i40e_update_link_infoJacob Keller
This call is made just prior to running i40e_link_event. In i40e_link_event, we set hw->phy.get_link_info to true just prior to calling i40e_get_link_status, which conveniently runs i40e_update_link_info for us. Thus, we are running i40e_update_link_info twice, which seems like something we don't need to do...

2017-02-18i40e: enable mc magic pkt wakeup during power downJoshua Hay
This patch adds a call to the mac_address_write admin q function during power down to update the PRTPM_SAH/SAL registers with the MC_MAG_EN bit thus enabling multicast magic packet wakeup. A FW workaround is needed to write the multicast magic wake up enable bit in the PRTPM_SAH register. The FW expects the mac address write admin q cmd to be called first with one of the WRITE_TYPE_LAA flags and then with the multicast relevant flags. *Note: This solution only works for X722 devices currently. A PFR will clear the previously mentioned bit by default, but X722 has support for a WOL_PRESERVE_ON_PFR flag which prevents the bit from being cleared. Once other devices support this flag, this solution should work as well.
