BNX2: fix a Null Pointer for stats_blk
we have two processes to do:
P1#: ifconfig eth0 down; which will call bnx2_close, then will
, and set Null to stats_blk
P2#: ifconfig eth0; which will call bnx2_get_stats64, it will
use stats_blk.
In one case:
--P1#-- --P2#--
stats_blk(no null)
bnx2_free_mem
->bp->stats_blk = NULL
GET_64BIT_NET_STATS
then it will cause 'NULL Pointer' Problem.
it is as well with 'ethtool -S ethx'.
Allocate the statistics block at probe time so that this problem is
impossible
