How to get to Longyang Road Exhibition Center in Shanghai Hongqi

1. I use BW, so far I haven't used any other mines. I believe BW mine has been doing a good job, no worse than other mines, and the service is fast! It's fast to make money! It will be better in the future.

2. Metro Line 2 (- - Metro Line 7)
follow the signs to Hongqiao Railway Station of Metro Line 2, take Metro Line 2 (Guanglan Road direction) at Hongqiao Railway Station, get off at Longyang Road station at 17, exit 9, walk along Longyang Road to the East, and then walk to Fangdian intersection
however, it will take about 10 minutes for the subway to get down. If you don't want to go, you can take line 2 to Longyang Road, then change to line 7, and take one stop to Huamu road. The New International Expo Center is at exit 2.

3. The distance is almost the same, but Pudong Airport is more convenient in the past. There is an airport bus to Longyang Road, which costs 20 yuan, and a taxi costs 100 yuan. From Shanghai Hongqiao Airport to Longyang Road Exhibition Hall, you can take 925 to people's Square, and then take Metro Line 2 to Longyang Road station. It costs about 100 yuan to take a taxi.

4. The network card is not attached

5.

bus line: Metro Line 2, the whole journey is about 27.0km

1. Walk about 210m from Shanghai Hongqiao Station to Hongqiao Railway Station

2. Take Metro Line 2, after 15 stops, to Shanghai Science and Technology Museum Station

3. Walk about 1.5km to Shanghai New International Exhibition Center

6.

Take Metro Line 2 (Guanglan Road direction) at Hongqiao Railway Station, get off at Longyang Road station, transfer to Metro Line 7 (Huamu road direction), get off at Huamu Road Station (exit 4), hundreds of meters to the East is

please take it, thank you

You can use the ethtool command to view, using the format ethtool network interface name

for example, eth0 is the name of the network card, and ifconfig is used to view the current network card

speed represents the bandwidth of network card, plex represents the working mode, and supported link modes represents the supported working mode

extended information:

other usages of ethtool command:

1. Query network port location: ethtool - P ethx

this command is mostly used to manage server hosts with multiple network ports. Due to the large number of network ports on the backplane, sometimes we don't know which physical port corresponds to eth0 or other device number, so we can use this command to query

usage: ethtool - P eth0

effect: the two indicators of the physical port corresponding to the device number eth0 will flash

2. Modify the network port rate: ethtool - s

this command is mostly used to manually set the network rate. Generally, the Gigabit network card supports three rates of 10 | 100 | 1000, and the unit is Mbps

usage: ethtool - s eth0 speed 1000 plex full autoneg off

effect: set the physical port corresponding to eth0 to 1000Mbps, full plex mode, and turn off auto negotiation

8. Take a look at this uint32_ What is the definition of T.
0x00000001? Although there are so many zeros written, it may not be stored as 32 bits when compiling programs (it is only possible), so to be on the safe side, it is necessary to force data type conversion for use in programs. It is possible to use eth in programs_ DMAIER_ Tie enforces that the data type must be uint32_ T's
in your case, it is possible that this definition is rendant, but sometimes it is necessary to transplant the program to other bit width chips, such as stm8, so the mandatory data type conversion is necessary. This enhances the portability of the code
