If it worked, then perhaps with a different device, or this one got a firmware update. Did a larger MTU actually work?
Or perhaps qmi_wwan gained support for the device and it's now using the CDC instead of PPP?
# lsusb -vvvv
...
Bus 003 Device 026: ID 1199:a001 Sierra Wireless, Inc.
...
CDC Ethernet:
iMacAddress 6 FFFFFFFFFFFF
bmEthernetStatistics 0x00000000
wMaxSegmentSize 1514
In any case -- it works the way it is supposed to. This device only supports the MTU of 1500.
Mass-moving bugs RHEL <= 7.6.0 to 7.7.0. As we are past RFE deadline for 7.7.0 and we should have no new features on 7.8.0, please evaluate if it's still wanted on RHEL7 and contact PM for exception. You may also move it to RHEL8 if that's wanted. Thanks! (In reply to Lubomir Rintel from comment #2) > If it worked, then perhaps with a different device, or this one got a > firmware update.
