[PATCH] net: phy: Fix truncation of large IRQ numbers in phy_attached_print()

Given NR_IRQS is 2048 on sparc64, and even 32784 on alpha, 3 digits is not enough to represent interrupt numbers on all architectures. Hence PHY interrupt numbers may be truncated during printing. Increase the buffer size from 4 to 8 bytes to fix this. Fixes: 5e369aefdce4818c ("net: stmmac:

[PATCH net-next 02/10] net: hns3: Add support for dynamically buffer reallocation

Current buffer allocation can only happen at init, when doing buffer reallocation after init, care must be taken care of memory which priv_buf points to. This patch fixes it by using a dynamic allocated temporary memory. Because we only do buffer reallocation at init or when setting up the DCB

tg3 pxe weirdness

Hi, I've got a machine with a Broadcom bcm5762c, using the tg3 driver, that fails to receive network packets under some very specific conditions. It works perfectly using a 1Gbps switch. If, however, it first uses PXE and then loads the Linux tg3 driver, and the switch is 100Mbps, it no longer

[PATCH net-next] bpf/verifier: improve disassembly of BPF_END instructions

print_bpf_insn() was treating all BPF_ALU[64] the same, but BPF_END has a different structure: it has a size in insn->imm (even if it's BPF_X) and uses the BPF_SRC (X or K) to indicate which endianness to use. So it needs different code to print it. Signed-off-by: Edward Cree
