Subject: net/ena/base: remove conversion of indirection table
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=585cacc67faadb1effe1cc47e817cbd380b8d354;p=dpdk.git

net/ena/base: remove conversion of indirection table

After the indirection table is being saved in the device, there is no
need to convert it back, as it's already saved in host_rss_ind_tbl
array.

As a result, the call to the ena_com_ind_tbl_convert_from_device() is
not needed.
