2019-03-07nfp: fix simple vNIC mailbox lengthDirk van der Merwe1-1/+1
The simple vNIC mailbox length should be 12 decimal and not 0x12. Using a decimal also makes it clear this is a length value and not another field within the simple mailbox defines. Found by code inspection, there are no known firmware configurations where this would cause issues.

2019-03-07net: stmmac: Avoid sometimes uninitialized Clang warningsNathan Chancellor1-3/+3

It's not wrong because the callbacks (get_timestamp and config_sub_second_increment respectively) are the ones that initialize the variables. While it's unlikely that the callbacks are ever going to disappear and make that condition false, we can easily avoid this warning by zero initialize the variables.

2019-03-07qede: Fix internal loopback failure with jumbo mtu configurationSudarsana Reddy Kalluru1-2/+5
Driver uses port-mtu as packet-size for the loopback traffic.

2019-03-07enic: fix build warning without CONFIG_CPUMASK_OFFSTACKArnd Bergmann1-3/+3
The enic driver relies on the CONFIG_CPUMASK_OFFSTACK feature to dynamically allocate a struct member, but this is normally intended for local variables. Building with clang, I get a warning for a few locations that check the address of the cpumask_var_t: drivers/net/ethernet/cisco/enic/enic_main.c:122:22: error: address of array 'enic->msix[i].affinity_mask' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion] As far as I can tell, the code is still correct, as the truth value of the pointer is what we need in this configuration. To get rid of the warning, use cpumask_available() instead of checking the pointer directly.

2019-03-07ravb: Decrease TxFIFO depth of Q3 and Q2 to oneMasaru Nagai1-1/+1
Hardware has the CBS (Credit Based Shaper) which affects only Q3 and Q2. When updating the CBS settings, even if the driver does so after waiting for Tx DMA finished, there is a possibility that frame data still remains in TxFIFO. To avoid this, decrease TxFIFO depth of Q3 and Q2 to one. This patch has been exercised this using netperf TCP_MAERTS, TCP_STREAM and UDP_STREAM tests run on an Ebisu board. No performance change was detected, outside of noise in the tests, both in terms of throughput and CPU utilisation.

This is needed for the following scenario: - SQ has an un-recovered error reported to the devlink health, resulting tx reporter state to be error. - Current channels (including this SQ) are closed - New channels are opened After that flow, the original error was "solved", and tx reporter state should be healthy. However, as it was resolved as a side effect, and not via tx reporter recover method, driver needs to inform devlink health about it.

2019-03-04get rid of legacy 'get_ds()' functionLinus Torvalds1-2/+2
Every in-kernel use of this function defined it to KERNEL_DS (either as an actual define, or as an inline function). It's an entirely historical artifact, and long long long ago used to actually read the segment selector valueof '%ds' on x86. Which in the kernel is always KERNEL_DS. Inspired by a patch from Jann Horn that just did this for a very small subset of users (the ones in fs/), along with Al who suggested a script. I then just took it to the logical extreme and removed all the remaining gunk. Roughly scripted with git grep -l '(get_ds())' -- :^tools/ | xargs sed -i 's/(get_ds())/(KERNEL_DS)/' git grep -lw 'get_ds' -- :^tools/ | xargs sed -i '/^#define get_ds()/d' plus manual fixups to remove a few unusual usage patterns, the couple of inline function cases and to fix up a comment that had become stale. The 'get_ds()' function remains in an x86 kvm selftest, since in user space it actually does something relevant.
