06ad12777f Warn if sign proto may be followed by padding 
For now, we check and tell the user. The actual fix should be for
sign proto to add padding before it's content, if required

a352ff3ed1 Fix frame variable count when varying frame lengths 
The frame variable count should be minimum of frame count and frame
length range size.

Unrelated, in case of random payload pattern, reuse
StreamBase::frameCount() which does the same calculation.

64fe90e5b7 Fix jumbo error being reported multiple times 
Also found and fixed another related bug where the loop to check pkt
size for trunc/jumbo ran for frameCount instead of
frameSizeVariableCount() - this change will reduce preflight check time
when frameSizeVariableCount is less than frameCount

Fixes #290

a757b9e353 UX: Warn for very short duration stream transmits 
Changed the default num_packets from 1 to 10, because otherwise the
default stream values will trigger this warning, which is not a good
experience for the user

e3a3a0cf1f Device Emulation (contd.): Fix frames not being truncated (introduced by recent changes in StreamBase::frameValue()); add test case for the same and add checksum/error check to pktlentest(s) 2016-01-27 20:39:54 +05:30

f1ff9e2616 Device Emulation (contd.) - StreamBase::frameValue() now returns truncated packet content and length instead of bailing out if the passed in buffer size is less than the packet length. This is useful for some of the device emulation code which needs packet content only uptil the IP header but not beyond, so we don't need to unnecessarily create the entire packet with payload for these cases 2016-01-15 09:37:43 +05:30

df24cf8b15 Feature: Variable Fields - any field of any protocol can now be varied by specifying it as a generic 8/16/32 bit field at a specified offset (relative to the protocol frame value) with a certain mask and a (initial) value alongwith count and step; this is working code - but incomplete. Bunch of FIXME/TODOs and testing pending 2015-05-26 21:43:37 +05:30

a9da643fb2 Feature: Reserve Ports for cooperative use of shared drone. If a port is reserved the GUI will display the username of the owner but others can still view and control the port; in other words, we just potentially prevent unintentional usage of other people's ports, users still need to play nice with each other!
