Commit 846742f7e32f ("selftests: drv-net: add a warning for
bkg + shell + terminate") added a warning for bkg() used
with terminate=True. The tso test was missed as we didn't
have it running anywhere in NIPA. Add exit_wait=True, to avoid:
# Warning: combining shell and terminate is risky!
# SIGTERM may not reach the child on zsh/ksh!
getting printed twice for every variant.

The device type for IPv4 GRE is "gre" not "ipgre",
unlike for IPv6 which uses "ip6gre".
Not sure how I missed this when writing the test, perhaps
because all HW I have access to is on an IPv6-only network.

Add a simple test for TSO. Send a few MB of data and check device
stats to verify that the device was performing segmentation.
Do the same thing over a few tunnel types.
Injecting GSO packets directly would give us more ability to test
corner cases, but perhaps starting simple is good enough?

Note that the test currently depends on the driver reporting
the LSO count via qstat, which appears to be relatively rare
(virtio, cisco/enic, sfc/efc; but virtio needs host support).
