For example the default link-layer header type for Ethernet interfaces is now DOCSIS.
And, given that the typical list of link-layer header types has one entry in it, and the typical entries have between 2 (Ethernet and DOCSIS) and 3 or 4 (for 802.11 with various radio headers, in monitor mode) the performance difference is probably negligible. I'd say that *all* lists presented to users should be presented in the same order as the data list used to generate the list shown to the user - and if those lists are long enough that the difference between prepending and appending makes a performance difference, that might get lost in the time it takes to show that huge list on the screen, complete with a scrollbar to let the user see all the entries.... ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
