Move modprobe.d/no-copybreak to vyatta-cfg-system package
It is really part of interfaces not vyatta-cfg

Since these drivers initially -# allocate a buffer size that is larger than the largest possible -# packet, this scheme returns that large buffer to the pool quickly, -# and uses a smaller one. -# -# The primary benefit of copybreak is better memory utilization. On -# systems where the data is ultimately going to be copied out to user -# space, the copybreak scheme is "low cost" because it has the side -# benefit of priming the cache for that later copy.

And on modern systems the memory savings -# is rarely an important consideration. -# -# Some of the drivers that employ copybreak make the feature -# configurable via a module parameter. This file disables copybreak -# in some of those drivers. Generally this results in an improvement -# in forwarding performance for traffic using these drivers. -# - -options 3c515 rx_copybreak=0 -options 3c59x rx_copybreak=0 -options cxgb copybreak=0 -options e1000 copybreak=0 -options e1000e copybreak=0 -options epic100 rx_copybreak=0 -options fealnx rx_copybreak=0 -options hamachi rx_copybreak=0 -options ixgb copybreak=0 -options natsemi rx_copybreak=0 -options pcnet32 rx_copybreak=0 -options r8169 rx_copybreak=0 -options sis190 rx_copybreak=0 -options sky2 copybreak=0 -options starfire rx_copybreak=0 -options sundance rx_copybreak=0 -options typhoon rx_copybreak=0 -options via-rhine rx_copybreak=0 -options via-velocity rx_copybreak=0 -options yellowfin rx_copybreak=0 - - - |
