Subject: baseband/fpga_5gnr_fec: remove filler from HARQ
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=ead7d1911df29d281f7e38a7456296d3058287b3;p=dpdk.git

baseband/fpga_5gnr_fec: remove filler from HARQ

Removed filler bits from HARQ calculation on the N3000 FPGA since these
are already taken out by the deratematching step.
The change is only an optimization with no functional impact, no change
required on stable branches.
