2018-01-02ethernet/broadcom: Use zeroing memory allocator than allocator/memsetHimanshu Jha1-3/+2
Use dma_zalloc_coherent for allocating zeroed memory and remove unnecessary memset function. Done using Coccinelle. Generated-by: scripts/coccinelle/api/alloc/kzalloc-simple.cocci 0-day tested with no failures. Suggested-by: Luis R.

2017-10-14bnxt_en: Fix possible corruption in DCB parameters from firmware.Sankar Patchineelam1-5/+18
hwrm_send_message() is replaced with _hwrm_send_message(), and hwrm_cmd_lock mutex lock is grabbed for the whole period of firmware call until the firmware DCB parameters have been copied. This will prevent possible corruption of the firmware data. Fixes: 7df4ae9fe855 ("bnxt_en: Implement DCBNL to support host-based DCBX.")

2017-07-24bnxt_en: Set ETS min_bw parameter for older firmware.Michael Chan1-0/+6
In addition to the ETS weight, older firmware also requires the min_bw parameter to be set for it to work properly. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-07-24bnxt_en: Report firmware DCBX agent.Michael Chan1-3/+8
Report DCB_CAP_DCBX_LLD_MANAGED only if the firmware DCBX agent is enabled and running for PF or VF. Otherwise, if both LLDP and DCBX agents are disabled in firmware, we report DCB_CAP_DCBX_LLD_HOST and allow host IEEE DCB settings. This patch refines the current logic in the driver.

2017-05-17bnxt_en: Check status of firmware DCBX agent before setting DCB_CAP_DCBX_HOST.Michael Chan1-2/+4
Otherwise, all the host based DCBX settings from lldpad will fail if the firmware DCBX agent is running. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-24bnxt_en: Pass DCB RoCE app priority to firmware.Michael Chan1-1/+107
When the driver gets the RoCE app priority set/delete call through DCBNL, the driver will send the information to the firmware to set up the priority VLAN tag for RDMA traffic.

2017-03-09bnxt_en: Check if firmware LLDP agent is running.Michael Chan1-1/+1
Set DCB_CAP_DCBX_HOST capability flag only if the firmware LLDP agent is not running. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-12-05bnxt_en: Implement DCBNL to support host-based DCBX.Michael Chan1-0/+490
Support only IEEE DCBX initially. Add IEEE DCBNL ops and functions to get and set the hardware DCBX parameters. The DCB code is conditional on Kconfig CONFIG_BNXT_DCB. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
