Subject: net/ice/base: allow package copy to be used after resets
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=aeff2769f370ecc7e9c273e06e60bdaeb044c1c0;p=dpdk.git

net/ice/base: allow package copy to be used after resets

For components that make a copy of an external pipeline package file
(i.e.  the Linux and FreeBSD drivers), save the size of the package
file along with the copy so that both can be used when calling
ice_init_pkg() after a CORER/GLOBR reset.
Also, do not free the copy of the package file in ice_init_pkg()
since it is needed afterward for subsequent resets.
