Fixes: 06554d381d97 ("ixgbe: speed up non-vector Tx")
icc (icc (ICC) 16.0.1 20151021) is generating following compile error:
"
CC ixgbe_rxtx.o
.../drivers/net/ixgbe/ixgbe_rxtx.c(153): error #3656: variable
"free" may be used before its value is set
(nb_free > 0 && m->pool != free[0]->pool)) {
^
"
Indeed this is a false positive and code is correct.
"nb_free" check prevents the free[] access before its value set.
But the patch is just for compiler to remove compiler error.
