From: Jiri Pirko Date: Sun, 8 Jul 2018 20:51:17 +0000 (+0300) Subject: mlxsw: spectrum_kvdl: Pass entry type to alloc/free X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=4b6b18692aec205b98dd333938b714af9d7aefe1;p=openwrt%2Fstaging%2Fblogic.git mlxsw: spectrum_kvdl: Pass entry type to alloc/free Future Spectrum-2 KVD linear manager implementation needs to know type of the entry to alloc and free. So define the types in an enum and pass it down to alloc and free functions. Once the entry type is passed down, KVDL common part knows sizes of each entry types, so replace size function arg with entry count.
