New Revision: 333819
URL: https://svnweb.freebsd.org/changeset/base/333819
Log:
Silence non-actionable warnings in vendor code
We can't modify vendor code so there's no signal in warnings from it.
Similarly -Waddress-of-packed-member is not useful on networking code
as access to packed structures is fundamental to its operation.
