[PATCH v2 net-next 0/2] smc-sysctl formatting and missing entries

[sawara04.o]

From: Kyoji Ogasawara <sawara04.o@gmail.com>

Hi,

this series updates SMC sysctl documentation in two small steps.

- patch 1 fixes indentation in the smcr_buf_type section
- patch 2 documents missing sysctl parameters limit_smc_hs and hs_ctrl,
  including values/defaults and hs_ctrl usage notes

No code or runtime behavior is changed.

Thanks,
Kyoji
