Andrea Claudi 4fb98f0895 devlink: fix segfault on health command
devlink segfaults when using grace_period without reporter

$ devlink health set pci/0000:00:09.0 grace_period 3500
Segmentation fault

devlink is instead supposed to gracefully fail printing a warning
message

$ devlink health set pci/0000:00:09.0 grace_period 3500
Reporter's name is expected.

This happens because DL_OPT_HEALTH_REPORTER_NAME and
DL_OPT_HEALTH_REPORTER_GRACEFUL_PERIOD are both defined as BIT(27).
When dl_opts_put() parse options and grace_period is set, it erroneously
tries to set reporter name to null.

This is fixed simply shifting by 1 bit enumeration starting with
DL_OPT_HEALTH_REPORTER_GRACEFUL_PERIOD.

This is a set of utilities for Linux networking.

How to compile this.
--------------------
1. libdbm

arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines.  Often this is in the db-devel package.

2. make

The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.

3. To make documentation, cd to doc/ directory , then
   look at start of Makefile and set correct values for
   PAGESIZE=a4		, ie: a4 , letter ...	(string)
   PAGESPERPAGE=2	, ie: 1 , 2 ...		(numeric)
   and make there. It assumes, that latex, dvips and psnup
   are in your path.

4. This package includes matching sanitized kernel headers because
   the build environment may not have up to date versions. See Makefile
   if you have special requirements and need to point at different
   kernel include files.
