34+# The driver smsc95xx, used by both Beagleboard XM and Pandaboard uses
35+# turbo mode by default, that enables multiple frames per Rx transaction,
36+# increasing performance but consuming more kernel memory.
37+# To avoid page allocation failures and smsc kevent drops we need to
38+# increase the minimum free system memory in the kernel to a higher value.
39+# If you're still having page allocation failures, try to increase this
40+# value to 12288 or even higher. You could also disable the driver's turbo
41+# mode, but decreasing the ethernet performance.
42+# If you encounter problems due to the settings please file a bug
43+# against the jasper-initramfs ubuntu package.
