4 | Subject: [PATCH] net: mipsnet: check packet length against buffer | ||
5 | |||
6 | When receiving packets over MIPSnet network device, it uses | ||
7 | receive buffer of size 1514 bytes. In case the controller | ||
8 | accepts large(MTU) packets, it could lead to memory corruption. | ||
9 | Add check to avoid it. | ||
