Bug #42861
openLibceph-common.so needs to use private link attribute when including dpdk static library
0%
Description
Libceph-common.so does not specify a link attribute containing the dpdk library,
dpdk global variables and functions will have a copy in libceph-common.so and the application.
It will cause the dpdk initialization to be abnormal：
