Revision 8ccb44e6f543eb355b04c0d08eb45598f3fe1fd1 authored by Matt Caswell on 01 December 2014, 23:58:05 UTC, committed by Matt Caswell on 03 December 2014, 09:43:47 UTC
Remove instances in libssl of the constant 28 (for size of IPv4 header + UDP)
and instead use the value provided by the underlying BIO. Also provide some
new DTLS_CTRLs so that the library user can set the mtu without needing to
know this constant. These new DTLS_CTRLs provide the capability to set the
link level mtu to be used (i.e. including this IP/UDP overhead). The previous
DTLS_CTRLs required the library user to subtract this overhead first.
