[PATCH net-next 0/9] bnxt_en: Updates.

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 1471 bytes --]

This patch series contains mainly NVRAM related features.  More
NVRAM error checking and logging are added when installing firmware
packages.  A new devlink hw health report is now added to report
and diagnose NVRAM issues.  Other miscellaneous patches include
reporting correctly cards that don't support link pause, adding
an internal unknown link state, and avoiding unnecessary link
toggle during firmware reset.

Edwin Peer (2):
  bnxt_en: introduce initial link state of unknown
  bnxt_en: Do not destroy health reporters during reset

Kalesh AP (4):
  bnxt_en: refactor error handling of HWRM_NVM_INSTALL_UPDATE
  bnxt_en: add more error checks to HWRM_NVM_INSTALL_UPDATE
  bnxt_en: parse result field when NVRAM package install fails
  bnxt_en: implement hw health reporter

Michael Chan (2):
  bnxt_en: Properly report no pause support on some cards
  bnxt_en: Eliminate unintended link toggle during FW reset

Vikas Gupta (1):
  bnxt_en: add an nvm test for hw diagnose

[PATCH net-next 1/9] bnxt_en: refactor error handling of HWRM_NVM_INSTALL_UPDATE

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 2687 bytes --]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

This is in anticipation of handling more "cmd_err" from FW in the next
patch.

[PATCH net-next 2/9] bnxt_en: add more error checks to HWRM_NVM_INSTALL_UPDATE

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 1388 bytes --]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

FW returns error code "NVM_INSTALL_UPDATE_CMD_ERR_CODE_ANTI_ROLLBACK"
in the response to indicate that HWRM_NVM_INSTALL_UPDATE command has
failed due to Anti-rollback feature. Parse the error and return an
appropriate error code to the user.

[PATCH net-next 3/9] bnxt_en: parse result field when NVRAM package install fails

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 3548 bytes --]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

Instead of always returning -ENOPKG, decode the firmware error
code further when the HWRM_NVM_INSTALL_UPDATE firmware call fails.
Return a more suitable error code to userspace and log an error
in dmesg.

devlink fw flashing allows for the msg to be reported directly 
to the user, that's more friendly than having to scan logs.

[PATCH net-next 4/9] bnxt_en: introduce initial link state of unknown

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 5227 bytes --]

From: Edwin Peer <edwin.peer@broadcom.com>

This will force link state to always be logged for initial NIC open.

[PATCH net-next 5/9] bnxt_en: Properly report no pause support on some cards

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 4969 bytes --]

Some cards are configured to never support link pause or PFC.  Discover
these cards and properly report no pause support to ethtool.  Disable
PFC settings from DCBNL if PFC is unsupported.

[PATCH net-next 6/9] bnxt_en: Eliminate unintended link toggle during FW reset

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 1528 bytes --]

If the flow control settings have been changed, a subsequent FW reset
may cause the ethernet link to toggle unnecessarily.  This link toggle
will increase the down time by a few seconds.

The problem is caused by bnxt_update_phy_setting() detecting a false
mismatch in the flow control settings between the stored software
settings and the current FW settings after the FW reset.  This mismatch
is caused by the AUTONEG bit added to link_info->req_flow_ctrl in an
inconsistent way in bnxt_set_pauseparam() in autoneg mode.  The AUTONEG
bit should not be added to link_info->req_flow_ctrl.

[PATCH net-next 7/9] bnxt_en: Do not destroy health reporters during reset

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 4330 bytes --]

From: Edwin Peer <edwin.peer@broadcom.com>

Health reporter state should be maintained over resets. Previously
reporters were destroyed if the device capabilities changed, but
since none of the reporters depend on capabilities anymore, this
logic should be removed.

This seems like a very weird recovery function.

I guess the FW automatically does auto-recovery and the driver 
has no control over it?

[PATCH net-next 9/9] bnxt_en: add an nvm test for hw diagnose

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 8643 bytes --]

From: Vikas Gupta <vikas.gupta@broadcom.com>

Add an NVM test function for devlink hw reporter.
In this function an NVM VPD area is read followed by
a write. Test result is cached and if it is successful then
the next test can be conducted only after HW_RETEST_MIN_TIME to
avoid frequent writes to the NVM.

You seem to execute a self-test from the .diganose callback.
That really seems like an abuse of the API. It's not hard to
