Some dpipe's global header values need special formatting, for example
Ethernet and IP addresses. This patchset adds support for IPv4/6 and
Ethernet's special format.
Arkadi Sharshevsky (4):
devlink: Make match/action parsing more flexible
devlink: Add support for special format protocol headers
devlink: Update devlink UAPI file
devlink: Add support for protocol IPv4/IPv6/Ethernet special formats

This patch decouples the match/action parsing from printing. This is
done as a preparation for adding the ability to print global header
values, for example print IPv4 address, which require special formatting.

In case of global header (protocol header), the header:field ids are used
to perform lookup for special format printer. In case no printer existence
fallback to plain value printing.
