With the full chip reset during MAC address change, the automatic PHY reset during chip reset will cause a link down and bonding will not work properly as a result. With this reset_phy parameter, we can do a chip reset without link down when changing MAC address or MTU. Signed-off-by: Gary Zambrano Signed-off-by: Michael Chan Signed-off-by: David S.

If the starting nvram address offset happens to be the last dword of the page, the NVRAM_CMD_LAST bit will not get set in the existing code. This patch fixes the bug by changing the "else if" to "if" so that the last dword condition always gets checked. Signed-off-by: Michael Chan Signed-off-by: David S.
