From a5a86ab1cba969d8fd1ac51249239fa2bcd2b0e2 Mon Sep 17 00:00:00 2001 From: zec Date: Mon, 22 Nov 2010 12:32:19 +0000 Subject: Allow for MTU sizes of up to ETHER_MAX_LEN_JUMBO (i.e. 9018) bytes to be configured on ng_eiface ifnets. The default MTU remains unchanged at 1500 bytes. Mark ng_eiface ifnets as IFCAP_VLAN_MTU capable, so that the associated vlan(4) ifnets may use full-sized Ethernet MTUs (1500 bytes).
