In the ice pmd driver code, ad ->is_safe_mode uninitialized ,with a random
value may cause ice_rss_Init() return error message "  not support in safe mode
" .To solve this problem, it is necessary to add code at the beginning of the
ice_dev_init()  "ad->safe_mode=0;"


//
I encountered this issue while debugging the e810 network card. The ice driver
code uses rte_socket_zmalloc, but this function does not initialize the memory
to 0 (but the annotation will clear 0? A bug ? only memset 0 in debug code),
which caused the above problem.
