The ixgb package somehow has ended up with a reference to ixgbe's third-party license which is basically an MIT license. However, there's no actual code in the ixgb package as it's a third-party binary. At this point we're suggesting that we remove that reference, as it's pretty hard to see how ixgbe's license could apply to ixgb in this state. This was noticed after 6926 which resulted in having the closed bins upset in certain conditions and no longer finding a similar file in the closed binaries.
