Subject: [dpdk-dev] [PATCH] net/ixgbe: fix build for gcc 4.8.5
Date: Tue, 14 Jan 2020 17:52:47 +0000	[thread overview]
Message-ID: <20200114175247.2930261-1-ferruh.yigit@intel.com> (raw)

Build error:
  In function ‘ixgbe_recv_pkts_lro_bulk_alloc’:
../drivers/net/ixgbe/ixgbe_rxtx.c:2209:24:
  error: ‘next_sc_entry’ may be used uninitialized in this function
  [-Werror=maybe-uninitialized]
    next_sc_entry->fbuf = first_seg;
                        ^
http://mails.dpdk.org/archives/test-report/2020-January/113891.html

This is a compiler false positive and error not seen by newer compilers,
or clang but to fix the warning initializing the complained variable.

According git bisect, no idea how:
Fixes: 8a2e7ce976fd ("net/ixgbe: avoid multiple definitions of bool")
