Commit Message

Deepak R Varma Oct. 20, 2022, 7:52 a.m. UTC 
  Follow the Linux Kernel coding style variable naming convention instead
of using camelCase style. Issue reported by checkpatch script for
these variables:
        tagLen, tagType, networkAddr, ipAddr, macAddr

Signed-off-by: Deepak R Varma <drv@mailo.com>
---

Changes in v3:
   -- None

Changes in v1 [actually v2]:
   1. Improve patch description per feedback from julia.lawall@inria.fr
