stable inclusion from stable-5.10.67 commit 3841dfa7eb5c93044bb28a3bf5400eb8add3a85e bugzilla: 182619 https://gitee.com/openeuler/kernel/issues/I4EWO7
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 95413846cca37f20000dd095cf6d91f8777129d7 ]
The program type cannot be deduced from 'tx' which causes an invalid argument error when trying to load xdp_tx.o using the skeleton. Rename the section name to "xdp" so that libbpf can deduce the type.
