Subject: net/bnxt: fix resetting mbuf data offset
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=3cefa72935fde04824fdfbee9c435c08278ab3c2;p=dpdk.git

net/bnxt: fix resetting mbuf data offset

Reset mbuf->data_off before handing the Rx packet to the application.
We were not doing this in the TPA path. It can cause applications
using this field for post processing to work incorrectly.
