Browse Source 
Michael Chan says:

====================
bnxt_en: updates for net-next.

Non-critical bug fixes, improvements, a new ethtool feature, and a new
device ID.

v2: Fixed a bug in bnxt_get_module_eeprom() found by Ben Hutchings.

Ajit Khaparde (2):
  bnxt_en: Add Support for ETHTOOL_GMODULEINFO and ETHTOOL_GMODULEEEPRO
  bnxt_en: Report PCIe link speed and width during driver load

Michael Chan (6):
  bnxt_en: Reduce maximum ring pages if page size is 64K.
  bnxt_en: Improve the delay logic for firmware response.
  bnxt_en: Fix length value in dmesg log firmware error message.
  bnxt_en: Simplify and improve unsupported SFP+ module reporting.
  bnxt_en: Add BCM57314 device ID.
  bnxt_en: Use dma_rmb() instead of rmb().

Satish Baddipadige (1):
  bnxt_en: Fix invalid max channel parameter in ethtool -l.
