[netdevice] Limit MTU by hardware maximum frame length

2017-01-25T14:55:09+00:00

Separate out the concept of "hardware maximum supported frame length" and "configured link MTU", and limit the latter according to the former. In networks where the DHCP-supplied link MTU is inconsistent with the hardware or driver capabilities (e.g. a network using jumbo frames), this will result in iPXE advertising a TCP MSS consistent with a size that can actually be received. Note that the term "MTU" is typically used to refer to the maximum length excluding the link-layer headers; we adopt this usage. Signed-off-by: Michael Brown

[legal] Relicense files under GPL2_OR_LATER_OR_UBDL

2015-03-02T16:35:29+00:00

These files cannot be automatically relicensed by util/relicense.pl since they either contain unusual but trivial contributions (such as the addition of __nonnull function attributes), or contain lines dating back to the initial git revision (and so require manual knowledge of the code's origin).
