Subject: IB/ipoib: Change number of TX wqe to 64
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b9595c5bac87af09cc3e82553244893b76632df6;p=linux.git

IB/ipoib: Change number of TX wqe to 64

NAPI budget is 64 packets, while maximum polling size for
the send CQ is 16. Let's bring them in sync, so the NAPI
budget will be reused completely.
