2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: Stephen Hemminger <redacted> Based on commit b63365a2d60268a3988285d6c3c6003d7066f93a upstream, but drastically cut down for 2.6.27.y The bridge device always causes a warning because when it is first created it has the no checksum flag set along with all the segmentation/fragmentation offload bits. The code in register_netdevice incorrectly checks for only hardware checksum bit and ignores no checksum bit. Similar code is already in 2.6.28: commit b63365a2d60268a3988285d6c3c6003d7066f93a net: Fix disjunct computation of netdev features Signed-off-by: Stephen Hemminger <redacted> Cc: David Miller <davem@davemloft.net> Cc: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> --- net/core/dev.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
