Haiyang Zhang says: ==================== hv_netvsc: Ethtool handler to change UDP hash levels The patch set adds the functions to switch UDP hash level between L3 and L4 by ethtool command. UDP over IPv4 and v6 can be set differently. The default hash level is L4. We currently only allow switching TX hash level from within the guests. The ethtool callback function is triggered by command line, and update the per device variables of the hash level. On Azure, fragmented UDP packets is not yet supported with L4 hashing, and may have high packet loss rate. Using L3 hashing is recommended in this case. This ethtool option allows a user to make this selection. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

We currently only allow switching TX hash level from within the guests. On Azure, fragmented UDP packets have high loss rate with L4 hashing. Using L3 hashing is recommended in this case. For example, for UDP over IPv4 on eth0: To include UDP port numbers in hasing: ethtool -N eth0 rx-flow-hash udp4 sdfn To exclude UDP port numbers in hasing: ethtool -N eth0 rx-flow-hash udp4 sd To show UDP hash level: ethtool -n eth0 rx-flow-hash udp4 Signed-off-by:

Veerasenareddy Burru says: ==================== liquidio: VF driver will notify NIC firmware of MTU change Make VF driver notify NIC firmware of MTU change. Firmware needs this information for MTU propagation and enforcement. The first patch in this series moves a macro definition to a proper place to prevent a build error in the second patch which has the code that sends the notification. Change Log: V1 -> V2 * Add "From:" line to patch #1 and #2 to give credit to the author. * In patch #2, order local variable declarations from longest to shortest line. ==================== Signed-off-by: -

The macro LIO_CMD_WAIT_TM is not specific to the PF driver; it can be used by the VF driver too, so move its definition from a PF-specific header file to one that's common to PF and VF. Signed-off-by:

Aviad Krawczyk says: ==================== Huawei HiNIC Ethernet Driver The patch-set contains the support of the HiNIC Ethernet driver for hinic family of PCIE Network Interface Cards. The Huawei's PCIE HiNIC card is a new Ethernet card and hence there was a need of a new driver. The current driver is meant to be used for the Physical Function and there would soon be a support for Virtual Function and more features once the basic PF driver has been accepted.

The JIT compiler emits ARM 32 bit instructions. Currently, It supports eBPF only. Classic BPF is supported because of the conversion by BPF core. This patch is essentially changing the current implementation of JIT compiler of Berkeley Packet Filter from classic to internal with almost all instructions from eBPF ISA supported except the following BPF_ALU64 | BPF_DIV | BPF_K BPF_ALU64 | BPF_DIV | BPF_X BPF_ALU64 | BPF_MOD | BPF_K BPF_ALU64 | BPF_MOD | BPF_X BPF_STX | BPF_XADD | BPF_W BPF_STX | BPF_XADD | BPF_DW Implementation is using scratch space to emulate 64 bit eBPF ISA on 32 bit ARM because of deficiency of general purpose registers on ARM. Currently, only LITTLE ENDIAN machines are supported in this eBPF JIT Compiler. Tested on ARMv7 with QEMU by me (Shubham Bansal). Testing results on ARMv7: 1) test_bpf: Summary: 341 PASSED, 0 FAILED, [312/333 JIT'ed] 2) test_tag: OK (40945 tests) 3) test_progs: Summary: 30 PASSED, 0 FAILED 4) test_lpm: OK 5) test_lru_map: OK Above tests are all done with following flags enabled discreatly. 1) bpf_jit_enable=1 a) CONFIG_FRAME_POINTER enabled b) CONFIG_FRAME_POINTER disabled 2) bpf_jit_enable=1 and bpf_jit_harden=2 a) CONFIG_FRAME_POINTER enabled b) CONFIG_FRAME_POINTER disabled See Documentation/networking/filter.txt for more information.

When building the kernel for Sparc using gcc 7.x, the build fails with: arch/sparc/kernel/pcic.c: In function ‘pcibios_fixup_bus’: arch/sparc/kernel/pcic.c:647:8: error: ‘cmd’ may be used uninitialized in this function [-Werror=maybe-uninitialized] cmd |= PCI_COMMAND_IO; ^~ The simplified code looks like this: unsigned int cmd; [...] pcic_read_config(dev->bus, dev->devfn, PCI_COMMAND, 2, &cmd); [...] cmd |= PCI_COMMAND_IO; I.e, the code assumes that pcic_read_config() will always initialize cmd. But it's not the case. Looking at pcic_read_config(), if bus->number is != 0 or if the size is not one of 1, 2 or 4, *val will not be initialized. As a simple fix, we initialize cmd to zero at the beginning of pcibios_fixup_bus. Signed-off-by:Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by:
