Subject: [PATCH] net/bnxt: fix double increment of idx during Tx ring alloc
[ upstream commit 1005d96445e9df72d9a907e0c82843528efed939 ]
We are incrementing idx twice while allocating Tx rings.
Since this is passed to the firmware, it may cause unexpected behavior.
Fixes: daef48efe5e5 ("net/bnxt: support set MTU")
