Subject: r8152: reduce the number of Tx
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1764bcd9fe0fa075b3c847836b646c386f7a672b;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

r8152: reduce the number of Tx

Because the Tx has the features of stopping queue and aggregation,
We don't need many tx buffers. Change the tx number from 10 to 4
to reduce the usage of the memory. This could save 16K * 6 bytes
memory.
