Subject: [PATCH 2/2] selftests: net: tun: don't abort XFAIL cases

From: Sun Jian <[email-masked]>
Date: Sun, 22 Feb 2026 19:18:47 +0800

The tun UDP tunnel GSO fixture contains XFAIL-marked variants intended to
exercise failure paths (e.g. EMSGSIZE / "Message too long").
Using ASSERT_EQ() in these tests aborts the subtest, which prevents the
harness from classifying them as XFAIL and can make the overall net: tun
test fail.

Switch the relevant ASSERT_EQ() checks to EXPECT_EQ() so the subtests
continue running and the failures are correctly reported and accounted
as XFAIL where applicable.
