X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=73dbb5e1627a35c8ab81f3813c096e9e7aaabaaa;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

bnx2x: fix crash while ethtool -t

commit 2df1a70aaf70e8dff11b89b938a5f317556ee640  "bnx2x: Support
for byte queue limits" has introduced an asymmetry in usage of
netdev_tx_completed_queue and netdev_tx_sent_queue. Missing
call to netdev_tx_sent_queue causes the crash during ethtool -t.

The patch adds the missing call.
