net: use core MTU range checking in misc drivers
firewire-net: - set min/max_mtu - remove fwnet_change_mtu nes: - set max_mtu - clean up nes_netdev_change_mtu xpnet: - set min/max_mtu - remove xpnet_dev_change_mtu hippi: - set min/max_mtu - remove hippi_change_mtu batman-adv: - set max_mtu - remove batadv_interface_change_mtu - initialization is a little async, not 100% certain that max_mtu is set in the optimal place, don't have hardware to test with rionet: - set min/max_mtu - remove rionet_change_mtu slip: - set min/max_mtu - streamline sl_change_mtu um/net_kern: - remove pointless ndo_change_mtu hsi/clients/ssi_protocol: - use core MTU range checking - remove now redundant ssip_pn_set_mtu ipoib: - set a default max MTU value - Note: ipoib's actual max MTU can vary, depending on if the device is in connected mode or not, so we'll just set the max_mtu value to the max possible, and let the ndo_change_mtu function continue to validate any new MTU change requests with checks for CM or not. Note that ipoib has no min_mtu set, and thus, the network core's mtu > 0 check is the only lower bounds here. mptlan: - use net core MTU range checking - remove now redundant mpt_lan_change_mtu fddi: - min_mtu = 21, max_mtu = 4470 - remove now redundant fddi_change_mtu (including export) fjes: - min_mtu = 8192, max_mtu = 65536 - The max_mtu value is actually one over IP_MAX_MTU here, but the idea is to get past the core net MTU range checks so fjes_change_mtu can validate a new MTU against what it supports (see fjes_support_mtu in fjes_hw.c) hsr: - min_mtu = 0 (calls ether_setup, max_mtu is 1500) f_phonet: - min_mtu = 6, max_mtu = 65541 u_ether: - min_mtu = 14, max_mtu = 15412 phonet/pep-gprs: - min_mtu = 576, max_mtu = 65530 - remove redundant gprs_set_mtu CC: netdev@vger.kernel.org CC: linux-rdma@vger.kernel.org CC: Stefan Richter <stefanr@s5r6.in-berlin.de> CC: Faisal Latif <faisal.latif@intel.com> CC: linux-rdma@vger.kernel.org CC: Cliff Whickman <cpw@sgi.com> CC: Robin Holt <robinmholt@gmail.com> CC: Jes Sorensen <jes@trained-monkey.org> CC: Marek Lindner <mareklindner@neomailbox.ch> CC: Simon Wunderlich <sw@simonwunderlich.de> CC: Antonio Quartulli <a@unstable.cc> CC: Sathya Prakash <sathya.prakash@broadcom.com> CC: Chaitra P B <chaitra.basappa@broadcom.com> CC: Suganath Prabu Subramani <suganath-prabu.subramani@broadcom.com> CC: MPT-FusionLinux.pdl@broadcom.com CC: Sebastian Reichel <sre@kernel.org> CC: Felipe Balbi <balbi@kernel.org> CC: Arvid Brodin <arvid.brodin@alten.se> CC: Remi Denis-Courmont <courmisch@gmail.com> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.
